There was a time (in 2009, I think) when this blog was primarily a round-up of Scottish subsamples from UK opinion polls of Westminster voting intention. It would be a bit difficult to sustain that now, given that there's a YouGov poll virtually every day. However, I thought you might enjoy the latest one (fieldwork was carried out yesterday and the day before) -

Did someone say something about a 'Scomnishambles'?
The poll also shows that Scots are less likely than respondents from any other region of the UK to think that British troops are "winning" in Afghanistan, or that the war is winnable.
