Politics are, generally, not my passion, and Megan McArdle nails it when she explains why:
I'll probably vote for Obama, but not with any expectation that I'll like the result very much. I am not excited about this election. I do not believe that my vote is going to immanentize the eschaton. I do not think that I am engaged in a titanic battle, in which the forces of good must beat back the cosmic evil that threatens to engulf us all. I think I'm deciding which of two politicians to hand a lot of power I don't want either of them to have.
It should be possible to debate the issues in this election at a level above "My guy's awesome and your guy is a big fat doody-head". But it doesn't seem to be. I find this profoundly depressing.
