Obviously you're not volver and I respect your point of view but there plainly are a lot of people who vote based on emotion rather than cold hard economics and experience of current Scottish government. It's the only explanation I can think of.
If you substitute "UK" for "Scottish", that also seems to be the reason some people are still wanting to vote for the UK Tory party, so you can't just think that only Scots can be, as you seem to think, sentimental rather than sensible when it comes to voting, Aveline.
