A new Britain-wide YouGov poll is out today, so this may be a good moment to round-up the Scottish subsamples that have been published since my last update. There have only been a couple...
Ipsos-Mori: SNP 43%, Labour 24%, Conservatives 23%, Liberal Democrats 9%
YouGov: SNP 36%, Labour 28%, Conservatives 25%, Liberal Democrats 5%, UKIP 4%, Greens 1%
That means nineteen subsamples in a row have put the SNP in an outright lead. Just the usual reminder - any individual subsample should not be regarded as reliable, but an aggregate/average of a large number of subsamples can give you a rough indication of what is happening. The sheer consistency of the SNP lead in subsamples since early September is probably indicative of quite a healthy SNP advantage on the ground, and is very much in line with the message from full-scale Scottish polls (although admittedly we haven't had any of those for a few weeks).
Are there any clouds on the horizon? Obviously the hysteria over Alex Salmond's new TV show has only just happened, so we'll have to wait and see how that plays out. It goes without saying that the criticisms of Salmond are hypocritical bilge given that leading politicians from all major parties have been willingly interviewed on the same channel, but on the other hand it is unusual (probably unprecedented) for Nicola Sturgeon to put out a personal statement distancing herself from something Salmond has done. She and her advisers may have thought that was a safety-first approach, but I suspect the truly dangerous thing is for parties to allow themselves to look divided. However, it's a very polite division on a relatively minor issue, so in spite of the mainstream media's valiant demands that their readers and viewers should care about this, I expect the likelihood is that we'll look back on it as a 72-hour wonder.
