I am a Democrat and voted for Dean Barkley in this race. I like Franken's passion but other than the fact that he's part of the party I generally agree with, he doesn't have anything else going for him. Coleman I don't really like that much, though I think people are a bit unfair to him. Yes, he's a Republican. But he's still more centrist than most Republicans. Barkley, on the other hand, lined right up with my viewpoints: Socially very liberal (moreso than the Democrats, advocating an end to the war on drugs and looser gun control), fiscally very conservative. I imagine a lot of Republicans disillusioned from the past eight years may have voted for Barkley rather than give their vote to a Democrat.
If Coleman wins by a tiny margin I'll be unhappy because I was conflicted about whether to vote for Barkley or Franken. But I decided, when I gave my vote to Barkley, that I wouldn't whine and complain about Coleman since I could have voted against him but didn't.
To those who say I threw my vote away: Fuck you. I voted with my principles. The fact that Barkley got such a large percentage of the vote, despite this being the hardest-fought senatorial battle in the entire country, says a lot about what Minnesotans think of the status quo.
