COMMENT:
There's nothing like opinion polls to get the chattering classes' gums beating.
The wide variation between the Newshub-Reid Research poll and 1 NEWS' Colmar Brunton last month had them frothing at the mouth. National loved the latter, while Labour loved the former - and the chatterers probably had the same feeling that Jim Bolger did after the 1993 election when he exclaimed "Bugger the pollsters".
It's the behind-the-scenes polls the parties have done for them that make the most interesting reading though, with their focus groups and the like.
As National heads back into its caucus today after a three-week break there'll be a lot of reflection as news of the Labour-commissioned UMR Research poll does the rounds.
