Here's one little statistic that shows how much Yes have to do to win.
At the last Scottish election much was made of the SNP's performance in NE Scotland - yet when you total all the votes up the SNP only achieved 52% of the vote in what is seen as their stronghold. Now I know that votes for the SNP (or other parties for that matter) may not translate in to Yes (or No) votes. It does, however, seem to me that the Yes campaign, despite the landslide for the SNP, have always had an uphill fight to turn things round in the 3 years since those elections. I still stand by my prediction of a No win - I have said by 57-43 (excluding spoilt papers including mine). Even if that were the result it would not be a disaster for Yes - either a platform to come back in future or to negotiate further powers if (more like when) the SNP win the next Scottish election. Whatever happens I think the status quo won't survive in its present form.
