If you live in Scotland and are hacked off with Labour, won't vote Tory and think the Lib Dems are nothing more than a bunch of whores who work without pay. BUT. You don't want independence. What is your option? Green?
So UKIP is intending to field candidates in all Scottish constituencies. Well it's a good gamble, the election up there is wide open. They got a full 10% of the vote in the EU elections and they might take quite a lot of Tory voters who won't vote Tory.
In the end I just think they will fracture most of the votes and make the whole thing even more unpredictable. But that is half the fun isn't it? Just so long as Labour gets a damned good kicking I'll be happy.
