Just thought I'd pass on a snippet of information sent to me by Stuart Dickson. He spotted on Stormfront Lite that the ESRC-funded Party Members Project has found that 5% of Labour members live in Scotland, as do 6% of Liberal Democrat members, and 10% of Conservative members. If those numbers are accurate (ie. if they're not a wildly misleading approximation or out of date), it's possible to use the UK-wide membership numbers to estimate how many members each party has in Scotland. It would put the Lib Dems on roughly 6500, Labour on about 28,500, and the Tories on about 10,000. That compares to an SNP membership of 118,000 as of August - roughly three times as much as the apparent combined membership of the unionist parties.
The Labour figure may seem a little higher than expected, but it's broadly in line with what we learned at the leadership election a few weeks ago, in which 17,664 full members cast a vote on a turnout of 62.3%. The party does seem to have demonstrated a certain cockroach-like resilience during its historic crisis over the last three-and-a-half years.
