Today's Scottish subsample from YouGov continues to show an entirely familiar picture : SNP 44%, Labour 28%, Conservatives 12%, UKIP 7%, Greens 4%, Liberal Democrats 4%. As usual, respondents who say that the SNP is the party they most closely identify with have been sharply downweighted, albeit not by quite as much as yesterday.
The most interesting finding is in relation to one of the supplementary questions. There is considerable regional variation across Britain on the subject of whether Ed Miliband would make the best Prime Minister, albeit not quite the variation you might expect if you believe the myth that Scotland is simply a "Labour heartland on holiday"...
Percentage of respondents who think Ed Miliband would make the best Prime Minister -
London : 18%
South (excluding London) : 14%
English Midlands and Wales : 23%
North of England : 26%
Scotland : 13%
So insisting that this election is a "straight choice between Ed Miliband and David Cameron" may not be the most promising strategy for Labour in Scotland - the overwhelming majority of people here (65%) want neither of them.
It looks like RevStu has a new full-scale Scottish poll in the pipeline, probably from Panelbase. So as the intensely irritating Wolf Blitzer would say : "We're going to be watching this one VERY closely. Standby."
