ACNielsen has published the second in its presumably monthly series of online polls, taken from a representative sample of volunteers who provide the company with market research data in exchange for prizes and gifts. The poll shows Labor’s two-party leading narrowing to 56-44 from 58-42 a month ago. Labor’s primary vote is down from 50 per cent to 47 per cent and the Coalition’s is up from 37 per cent to 41 per cent.
