I Followed a similar logic in the polling boothUp here, north of the Border we have two votes. One for constituency MSP and one for the also-rans known as List MSPs.
My first vote for constituency will be for Labour, tactical in that I want to try and unseat the incumbent, and useless, SNP guy. He has a large majority though so it will take quite a lot to ditch him.
Second vote will be for SC&U, where my first vote would have gone if there was a chance for the Tory guy.
