There was a Roy Morgan poll out yesterday showing a gap of 14 between National and Labour. Party support varied only slightly from the previous Morgan poll.
The Morgan poll differs hugely from the controversial Fairfax poll from a week or so ago which showed a gap of 27 points. This just goes to show how large a role polling methodology plays in these matters.
The other thing worthy of mention is how lazy the analysis is in these Morgan polls. Having gone to such a lot of effort to get the quantitative info, they just seem to give up when it comes to doing the qualitative work.
