By-election bloodbaths

The Pittwater by-election stands as a disaster of historic magnitude both for the New South Wales Liberal Party, which has lost its third-safest seat, and for the Poll Bludger, who has lost $25. Apologies are due to Alex McTaggart and to various journalists whose prescient remarks about the Liberals’ troubles received short shrift on this site.

In my defence, I was in good company – my assessment was echoed by Antony Green, whose recent Parliamentary Library background paper on New South Wales by-elections from 1965 to (early) 2005 provides historical perspective on the scale of the disaster. The paper notes that major parties have often declined to nominate candidates because they felt that leaving the field vacant for independents was the best chance of depriving their opponents of the seat. Until yesterday, the tactic had not been particularly successful. Antony lists 24 "one-sided" by-elections held in New South Wales between 1975 and 2004, to which two more were added at the triple M by-elections of September 17. Of these, the only defeat for a major party candidate was at last year’s Dubbo by-election, and this did not represent a loss for the relevant major party (the Nationals) because the previous member had also been an independent.

This should not come as a surprise, because newcomer independents traditionally win their seats on the back of major party preferences. Once they are privy to the advantages of incumbency it is not uncommon for independents to turn in results as good as that achieved yesterday by Alex McTaggart, but getting their foot in the door normally involves finishing second and then surging ahead on preferences from a third-placed major candidate. That McTaggart was able to skip this phase and outperform Paul Nicolaou on the primary vote underscores the magnitude of the catastrophe for the New South Wales Liberals.

As the Sun-Herald puts it, "the result has left poll specialists reaching for history books to find when a safe seat had swung so demonstrably against one of the major parties". In the Federal arena, the examples that spring to mind are Bass in 1975 (when Labor’s primary vote fell 17.5 per cent), Canberra in 1995 (when it fell 21.8 per cent) and Cunningham in 2002 (down 6.1 per cent, but with the result being a historic loss to the Greens). At State level, the Sunday Telegraph quotes Antony Green citing the Coffs Harbour by-election of 1990, when the National Party vote fell from 67.3 per cent to 37.4 per cent. But this was partly influenced by an increase in the number of candidates from two to seven, and the Nationals still won the seat by a two-party margin of 5.4 per cent.

Since my command of the subject is sketchy, I would be grateful if readers can help me put together a list of noteworthy State by-election massacres. Major disasters only please – as a rough guide, it will take a primary vote swing of at least 15 per cent to make the cut. To get the ball rolling, here are three examples that do spring to mind – note the home state bias.

Benalla, Victoria (13/5/2000). Locals were not pleased when Nationals leader Pat McNamara quit parliament not long after the unexpected defeat of the Kennett Government, and reacted by sending the party’s vote down from 57.4 per cent to 41.0 per cent and delivering the seat to Labor for the first time in its history. Unsuccessful Nationals candidate Bill Sykes would go on to narrowly recover the seat from Labor’s Denise Allen at the otherwise disastrous 2002 election.

Floreat, WA (16/5/1991). Now the member for the successor electorate of Churchlands, Liz Constable came to parliament in this safe Liberal seat at a by-election brought on by the death of Andrew Mensaros. Constable was the popular local choice for a Liberal preselection that instead went to the favoured candidate of controversial powerbroker Noel Crichton-Browne. She contested as an independent and scored an easy win with 49.0 per cent of the primary vote, with the Liberal vote falling from 63.3 per cent to 37.0 per cent in a field vacated by Labor.

Geraldton, WA (13/4/1991). Carmen Lawrence’s Labor Government was already reeling from the WA Inc fiasco when a botched reshuffle caused three dumped ministers to quit the Labor Party, depriving it of its parliamentary majority. Geraldton MP Jeff Carr quit parliament altogether, prompting a by-election at which the Labor vote fell from 47.6 per cent to 16.6 per cent, leaving the Liberal and National candidates to fight it out for first and second place. The narrow winner was Liberal candidate Bob Bloffwitch, who would go on to suffer an electoral meltdown of his own at the 2001 State election.

Surfers Paradise, Queensland (5/5/2001). Upon conceding defeat after the disastrous 2001 election, at which he had taken his party from 23 seats to 12, Nationals leader Rob Borbidge told supporters that his own seat of Surfers Paradise was among the casualties. This puzzled election watchers who correctly believed him to be about 5 per cent in front. It may have amounted to wishful thinking, as his resigned his leadership and parliamentary seat immediately upon his re-election. The resulting by-election reduced the National Party from a near primary vote majority (49.7 per cent) to the status of a minor party (8.0 per cent). Votes were lost to the first Liberal Party candidate in the seat since 1992, John-Paul Langbroek (21.2 per cent), and to Gold Coast mayor and independent candidate Lex Bell, who won the seat with 35.9 per cent of the vote. The result meant the end of the National Party as a force on the Gold Coast, although they still won’t admit it. The seat returned to the Coalition fold at the 2004 election partly because Bell had became mired in local scandals, but also because the Nationals left the field free to the Liberals, who again ran with Langbroek.

Bass Hill and Rockdale, New South Wales (2/8/1986). The writing was on the wall for Barrie Unsworth’s Labor Government after the two by-elections marking the departure of his predecessor, Neville Wran (Bass Hill), and another MP in a safe seat, Brian Bannon (Rockdale). Unsworth used Rockdale to make the necessary switch from the upper to lower house a la John Gorton in 1968, but received the shock of his life when a 17.1 per cent dive in the primary vote combined with hostile independent preferences to bring him to within 54 votes of defeat. The result in Wran’s old stronghold was even worse, with a 22.2 per cent drop on the primary vote delivering a 103 vote victory to the Liberal candidate. Although Unsworth was swept from office at the subsequent State election in 1988, both Bass Hill and Rockdale reverted to type and were easily won by Labor. Tip: Geoff Lambert.

. McTaggart Nicolaou CDP IND GRN DEM
Primary 40.2 38.2 8.2 6.0 7.5 0.9
Swing -22.3 +5.3 -6.5 -1.2
Two-Candidate 56.1% 43.9% 82% COUNTED

8.36pm. News report on ABC Online.

8.32pm. The last reporting booth, Avalon (the electorate’s second biggest), has added insult to injury – the only booth with a primary vote majority for McTaggart, his two-candidate vote was 65.6 per cent. His overall raw two-candidate vote is now up to 55.9 per cent, so it seems my calculations were doing their job.

8.30pm. Only the two-candidate result from Avalon still to come. I have McTaggart on 56.1 per cent, compared with a raw figure of 54.6 per cent.

8.23pm. I somehow failed to notice that the large (9.5 per cent) Avalon booth had yet to submit its results earlier. It’s the biggest booth in McTaggart’s Northern Ward and its result has further widened his lead.

8.15pm. Most of the two-party count is now in. The SEO has McTaggart with 54.4 per cent and Nicolaou on 45.6 per cent. Special votes evidently lean particularly in the Liberals’ favour because my projection has McTaggart on 53.0 per cent. Either way, the outcome is not in doubt. After earlier having laughed off Liberal talk of a primary vote below 40 per cent and a 46.5-53.5 defeat on two-candidate, I now promise never to disbelieve a politician again.

7.58pm. An ordinary night at the office for the Greens, whose supporters have evidently jumped on the Alex McTaggart bandwagon. Those who thought the Democrats had already hit rock bottom have been given cause to think again. Patricia Giles and Robert Dunn both polled disappointingly.

7.55pm. The last primary vote figures for the night are in, from Mona Vale (10.2 per cent) and Mona Vale Beach (3.4 per cent). Nicolaou at least led on the primary vote in these booths, but in both the Liberal vote was down 23.1 per cent.

7.50pm. Now to survey the damage. The Liberals did not do quite so badly outside of the Pittwater Council area – the lost about 15 per cent of the primary vote in Narrabean and 12.7 per cent in Terrey Hills. But within the council area their vote was down almost half, generally moving from the sixties to the upper thirties.

7.44pm. Well, I got one thing right – my preference estimates were all but perfect. Results from four booths show McTaggart getting 49.5 per cent (I gave him half), Nicolau getting 16.1 per cent (my guess was 16.6 per cent) and 34.4 per cent exhausting (33.3 per cent for me).

7.41pm. Another flurry of results leaves only two booths to be counted, one of which is Mona Vale, the electorate’s largest. But with McTaggart ahead on the primary vote, nothing can save the Liberals now.

7.22pm. Eight booths are in all of a sudden and it’s clear we have a boilover here – barring a miracle in the larger booths, McTaggart has won.

7.15pm. It might also be worth mentioning that the actual two-candidate vote at War Vetarans Home (616 votes) was 59.7 per cent for Nicolaou and 40.3 per cent for McTaggart.

7.11pm. Presumably the SEO is maintaining its habit of providing booth results in indigestible bursts. Allow me to while away the time with two small observations – a) the exhaustion rate is almost certain to be lower than the War Veterans Home reults suggest; b) the Scotland Island booth actually had an increase in turnout, from 198 to 219 voters, and dit not record a single informal vote.

7.00pm. There were 86 votes for the four minor candidates at War Veterans Home – of these 32 went to McTaggart, nine went to Nicolaou and 45 exhausted. A tiny sample, but if representative, it will mean that my two-party calculation flatters McTaggart. I will wait for another booth before I replace my estimates with the actual results.

6.41pm. Results from two quirky small booths are in. Scotland Island is particularly eccentric, having voted 47.7 per cent for the Greens in 2003. This time both their vote and the Liberal vote (from 30.1 per cent to 19.6 per cent) is way down. In the smaller War Veterans Home, the Liberal vote is down from 66.8 per cent to 53.6 per cent, enough to almost make it interesting if played out over the whole electorate. Also interesting to note that the booth is not in Pittwater Council.

Welcome to the Poll Bludger’s live coverage of the Pittwater by-election. Providing my internet connection behaves, the site will provide updates every few minutes on the progress of the count as each booth result comes in. The first of these should be in a little after 6.30pm EST. The table above will provide raw figures for the primary vote along with a two-candidate preferred calculation which assumes that a) the primary vote swing for or (more likely) against the Liberal Party will be the same in uncounted booths as in those for which results are available, and b) that half of the preferences of the four minor candidates will go to independent Alex McTaggart, a sixth will go to Liberal candidate Paul Nicolaou and a third will exhaust.

The above map provides a rough idea of Pittwater’s council ward boundaries, which should shed some light on local variations in voting patterns. The electorate also includes populated areas of neighbouring Warringah Council around Terrey Hills (part of which is beyond the western limit of the map) and Narrabean. The map also includes the locations of polling booths and provides percentages figure indicating each booth’s share of the total vote at the 2003 State election. There will be one change in the booth arrangements for the by-election, with the Lagoon Street booth (located a short distance north of the Narrabean booth) replaced by Narrabean Beach (located further south). The percentage figure provided for Narrabean Beach is that for Lagoon Street, hence the asterisk.

Both McTaggart and Greens candidate Natalie Stevens represent the Pittwater Council’s Northern Ward, where the tickets they led respectively polled 25.7 per cent and 18.6 per cent of the vote at last year’s council election. Christian Democratic Party candidate Patricia Giles is a former mayor who represents Central Ward, where her ticket polled an impressive 49.2 per cent. The remaining candidates are independent Robert Dunn, another former mayor, and Democrats candidate Mario Nicotra.

Pittwater dispatches

Those with a particular interest in Saturday’s Pittwater by-election are encouraged to drop by to this site after 6pm EST, from which time the numbers will be crunched booth-by-booth within seconds of their appearance on the State Electoral Office site (for some idea of how this will look, see the coverage of the triple M by-elections of September 17).

The by-election is being taken a lot more seriously than I had earlier anticipated, particularly after last week’s reports of internal polling showing the Liberals headed for defeat at the hands of independent candidate Alex McTaggart. This would not normally have been taken so seriously, but the figures came attached to a narrative widely favoured among the media: that the religious right has subverted the NSW Liberal Party in the wake of the Federal election outcome, and is about to get its come-uppance courtesy of environmentally conscious small-l Liberals of Sydney’s northern beaches. This sounds very much like a reprise of the unsuccessful "doctors’ wives" theory at the Federal election, which posited that affluent and educated voters were so disaffected over Iraq, Kyoto and asylum seekers that senior figures in the Government were in danger of losing their seats.

If the leak of internal polling was a tactical manoeuvre by a Liberal Party genuinely concerned for its hold on the seat, it might well have backfired by giving McTaggart a monopoly of media attention at the expense of a field that includes two other former mayors. It now seems certain that McTaggart will indeed harvest most of the purely negative anti-Liberal vote, whereas the Liberals would have been better served if this had split amongst as wide a range of rival contenders as possible. That at least will be my excuse for getting it wrong if McTaggart wins, but my prediction remains nonetheless.

A summary of noteworthy campaign shenanigans in the final week:

  • Alex McTaggart has lately been promoting himself as a man who can do business with the Government, and the Premier helped him demonstrate the point with an hour-long meeting followed by promises on "Mona Vale Hospital, the Currawong site and Careel Bay Marina". Many have questioned McTaggart’s judgement here, given the Liberals’ efforts to paint him as a Labor stalking horse. Christian Kerr of Crikey was particularly appalled by McTaggart’s decision to indulge in a photo opportunity with Roads Minister Joe Tripodi, almost going as far as to say it had single-handedly cost him the election. Tripodi’s popularity is such that Nationals MP Andrew Fraser received a sympathetic response following their recent confrontation on the floor of parliament, which most interstate obervers assumed would end his career.
  • Piers Akerman has weighted into the campaign for a second time in today’s Daily Telegraph, taking an ideological cudgel to those who would paint the NSW Liberal Party’s recent upheavals as a coup by right-wing extremists. After arguing that Brogden was responsible for his own demise, Akerman dismisses Alex McTaggart as "a political one-trick pony who was elected to the council after blocking Baywatch’s plans to film at Avalon, where he surfs".
  • Last week, Alex McTaggart reckoned leaked Liberal polling showing him ahead of their candidate was "a plot to scare the little old ladies into voting Liberal". Now, he says polling that he himself has done "anecdotally" shows he will "outpoll the Libs, we don’t even need preferences". McTaggart shocked readers of Saturday’s Manly Daily with the revelation that "if this was not a by-election and John Brogden was still the member, I would not be running".
  • Antony Green concurred with this site’s assessment when he told The Australian that the Liberals would "take a big hit with their vote", but would "probably win".
  • All minor players are specifically recommending a preference to McTaggart over Nicolaou.
  • The Poll Bludger’s form guide tip of the week: Paul Nicolaou. Centrebet is offering $2.20 for a Liberal win against $1.61 for McTaggart.
  • UPDATE (25/11/05): The Daily Telegraph’s Liberal sources say their position has "improved slightly since it became clear Mr McTaggart was ‘cuddling up to the Premier’"; the Sydney Morning Herald’s Liberal sources say they fear their primary vote will drop below 40 per cent; Centrebet’s Gerard Duffy says there has been "renewed interest in the Liberal candidate", and they are now offering $2.oo for a Liberal win against $1.72 for McTaggart.

    UPDATE (26/11/05): The flurry of late money for Nicolaou (including a $25 punt from the Poll Bludger) has continued, with Centrebet now offering $1.85 for both Nicolaou and McTaggart.

    Purported Pittwater party polling

    Reports of "leaked" internal Liberal polling for next Saturday’s Pittwater by-election have provoked a frisson of excitement among those with an interest in talking up the contest. The poll reportedly has Liberal candidate Paul Nicolaou trailing his most fancied independent rival, local mayor Alex McTaggart, with a 46.5-53.5 split on two-candidate preferred. The results were a gift from "a senior Liberal who did not want to be named" to Lisa Muxworthy of the Manly Times, who smartly cultivated her source by reporting it exactly the way he or she would have wanted – a close race with the outcome to be determined by the undecided, and no luxury of a protest vote for those who normally support the Liberals. Anne Davies of the Sydney Morning Herald spruiked the contest by telling us "the parochial peninsula electorate has shown in the past that it can record large swings when a new candidate is endorsed, particularly if they are not a local". This was presumably a reference to surfer Nat Young’s strong performance against Jim Longley at a by-election way back in 1986, when sewage pollution on local beaches was a national news story. Christian Kerr of Crikey has also invoked the spectre of Nat Young while making plenty of space available for those predicting a Liberal humiliation, citing word-of-mouth evidence to suggest a swing not far shy of 20 per cent.

    The Poll Bludger is not persuaded. It is axiomatic that leaked party polls are to be taken with a grain of salt, for reasons which hardly need explaining. Most of those reporting the Liberal figures seem to be conscious of this, with the Sydney Morning Herald providing a nice quote from Alex McTaggart about "a plot to scare the little old ladies into voting Liberal". I have a very particular theory on this occasion, which rests on two pillars – firstly, that the best lies are based on a foundation of truth; secondly, that political parties know this (and much else about the art of deception) better than anyone. On this basis, I suggest that the Liberals have indeed conducted polling that has them on 46.5 per cent, but that this is on the primary rather than the two-party preferred vote. This sounds about right – a sobering 12.9 per cent primary vote slump that would give the Liberals no cause for optimism about the 2007 election, but not enough to threaten their hold on so safe a seat. It would not be too hard to persuade an inquisitive journalist that all minor candidate votes should indeed be added to McTaggart’s two-candidate preferred score, since they will all "give" him their preferences. But in reality, 46.5 per cent would be enough for Nicolaou to win quite easily.

    This brings us back to the Nat Young precedent. Leaving aside the fact that some who will vote next Saturday were not even born in 1986, it is worth noting that Young actually fell some way short with 46.9 per cent of the two-candidate vote – an excellent result, but still a clear victory for the Liberals. More importantly, this was in the days when the opportunities of optional preferential voting had yet to catch on. Young gathered 72 per cent of preferences from the 33 per cent who voted for other candidates, with an exhaustion rate of just 4.1 per cent. These days, a third of that vote can be expected to disappear courtesy of those who "just vote one". Even assuming the Liberal poll results are not completely fictitious, it would be quite astonishing if they honestly accounted for this.

    Back in the JSCEM

    More bedtime reading on the contentious electoral reform proposals from the Liberal-dominated Joint Standing Committee on Electoral Matters. The inestimably estimable Dr Graeme Orr of Griffith University (who, as well as being big on electoral minutiae, also looks a bit like me) goes through the debate with a fine-tooth comb, and in doing so adds a rare note of sobriety to Margo Kingston’s Webdiary. And in case you missed it, committee chair Tony Smith mounted a less than persuasive rebuttal of criticisms from Brian Costar and Colin Hughes in The Age last week.

    Pittwater form guide

    The campaign for Saturday week’s Pittwater by-election limps on uneventfully, although some observers remain excited at the prospect of John Brogden’s demise causing a backlash sufficient to endanger the Liberal candidate, former party fund raiser Paul Nicolaou. Local ratepayers association types have been penning letters to the editor and badgering suburban newspaper journalists to vent their outrage that Nicolaou was until recently a resident of Lane Cove, scoring particularly well with last week’s revelation that he moved into his new Mona Vale address too late to get on the roll for the by-election. However, history suggests suburban voters don’t get terribly excited about this kind of thing and that a messy preselection outcome was the real prerequisite for a Liberal defeat, and this the party has managed to avoid. They are also boosted by a field of rival contenders that includes the mayor, two former mayors and another councillor besides. Since New South Wales has optional preferential voting, preference exhaustion from the scattered anti-Liberal vote will make it very difficult for any of the independents to cause Nicolaou real trouble.

    The candidates in ballot paper order:

    Alex McTaggart (Independent). Widely perceived as the main threat to the Liberal Party due to his current status as Pittwater Mayor. Despite his forceful denials, McTaggart has been subject to repeated suggestions that he is receiving help from the Labor Party. The most interesting was a small item in the Sun-Herald noting that postal vote applications sent out by McTaggart suggested access to the electronic electoral rolls, which are apparently available "only to the major parties". For what it’s worth, Piers Akerman reckons Pittwater Council is "significantly on the nose with ratepayers and is perceived as arrogant and uncaring", and that McTaggart is "seen as a councillor elected on a single NIMBY (not in my back yard) issue – a ban on television crews at his local beach, Avalon".

    Paul Nicolaou (Liberal). The Sydney Morning Herald reported that Nicolaou would shed as little as 5 per cent of the Liberal vote, according to "Labor polling" – though why they would bother to conduct any was not made clear.

    Patricia Giles (Christian Democratic). The former Pittwater mayor’s electoral record is better than incumbent Alex McTaggart’s, but she would surely be better off without the Fred Nile brand.

    Robert Dunn (Independent). A former mayor and Liberal Party member, Dunn told Lisa Muxworthy of the Manly Daily that he was running because he was "appalled" by the "contempt" the Liberal Party had shown Pittwater by nominating a Lane Cove resident. He is apparently no more pleased with the member for the corresponding Federal seat of Mackellar, Bronwyn Bishop, having scored a reasonable 7.7 per cent in his run against her at last year’s Federal election.

    Natalie Stevens (Greens). Stevens became the first Greens member on Pittwater Council at last year’s election, winning a seat in the five-member Northern Ward with 18.6 per cent of the vote.

    Mario Nicotra (Democrats). Nicotra was also the Democrats candidate for Mackellar at the Federal election. He tells the Manly Daily that Mona Vale Hospital "should be rebuilt as a showcase healing centre" incorporating, among other things, "complementary medicines, natural healing, homoeopathy, acupuncture and other services".

    First they came for the late enrollers

    Two opinion pieces in today’s papers give the thumbs down to major recommendations of the report of the Joint Standing Committee on Electoral Matters. In The Age, Colin Hughes and Brian Costar concede that the report "contains much useful information about the electoral system and makes sensible recommendations about how to improve it", but argue that moves to eliminate the seven-day period between the issue of the writs and the closure of the electoral roll threaten "Australia’s well-earned reputation as a world leader in democratic practice":

    The committee advanced two major justifications for abolishing the statutory period of grace. One was that by not keeping their enrolment up to date 284,110 souls were guilty of offences under the Electoral Act and should not be allowed any leeway. This excessive legalism runs counter to the sensible, long-established practice whereby the Australian Electoral Commission does not pursue prosecution for non-enrolment if the neglect is remedied.

    The committee also claims that the current arrangements "present an opportunity for those who seek to manipulate the roll to do so at a time where little opportunity exists for the AEC to undertake the thorough checking required ensuring (sic) roll integrity". This argument fails on at least two counts. First, the AEC, in its submission to the inquiry, stated categorically that it applies its established procedures during the seven-day period after the writs are issued “with the same degree of rigour as it does in a non-election period”. Second, the committee itself admits that there is minimal evidence of actual roll fraud, but insists that it must take measures to prevent it occurring in the future.

    This second assertion ignores the thorough review of the electoral roll conducted in 2002 by the Australian National Audit Office, which concluded "that, overall, the Australian electoral roll is one of high integrity, and can be relied on for electoral purposes". There are adequate safeguards in the current electoral laws and procedures to deal with any future attempts at fraud without stripping the vote from hundreds of thousands of citizens.

    Before we all start stocking up on firearms and tins of baked beans, Hughes and Costar note that a potential constitutional loophole promises salvation for our cherished democratic freedoms, should state governments choose to make use of it:

    This arises from the fact that the governor-general, on the advice of the prime minister, issues the writs for the House of Representatives and the four territory senators, but the state governors, acting on the advice of their premiers, issue the writs for Senate elections. The constitutional power clearly exists for one or more of the state premiers to advise their governors not to issue Senate writs for, say, seven days after the prime minister announces the election date, thereby keeping the rolls open in those states.

    Writing in the Australian Financial Review (not available online), Malcolm Mackerras differs from Hughes and Costar in that his "overall reaction is hostile", because the recommendations are "relentless in their pursuit of the electoral interests of the Liberal Party". Restrictions of space compel him to limit his criticisms to the familiar matter of full preferential above-the-line voting for the Senate:

    Such a change would massively drive up the informal vote. Why do we have this Faustian pact between the Liberal Party, the Democrats and the Greens? The Liberal Party wants to drive up the informal vote because that advances its electoral interests. The Democrats and the Greens are in the business of punishing Family First because, in their view, Steve Fielding won a seat in Victoria that they believe he should not have won. These politicians will vehemently deny my assessment …

    Lack of space prevents me from a full explanation of why I call chapter nine a disgrace. I content myself with three points. First, the chapter (page 230) grotesquely mis-describes the system of "first past the post" in an attempt to justify the prejudices of many of our politicians. Second, the chapter (pages 208, 210, 214 and 226) commits a real howler in using the term single transferable vote in a way that is not only internally inconsistent but flies in the face of the international literature on electoral systems. Third, the chapter gives some objections to the current (reasonably sensible) system of group voting tickets and then (page 216) says: "The decision of the Family First party in some states to favour a preference distribution to other minor parties that advocated policies radically at variance with Family First’s declared core values, may be an example of this type of strategic behaviour, and its consequences."

    No evidence is given. However, the main value of this sentence (not intended, of course) is that the politicians have given themselves away as to their target.

    Mackerras seems unusually relaxed about Family First’s success in winning a seat with neglible support thanks to huge volumes of preferences from oblivious voters. I would be interested to know if this is because space prohibited him from advocating what seems to me the obvious solution, namely optional preferential voting. For much, much more on this topic, see the comments thread for this earlier post.
