I haven't changed my mind, exactly, but I think it's fair to say I made up my mind due to discussions I've had, right here on A2K. I discuss politics here more than I do every other venue combined. Had you asked me three and a half years ago if I would vote for John McCain next month... I would have answered, in all likelihood, yes... with perhaps 90% confidence. And I'd have been very happy about the opportunity to do so. My politics have evolved a great deal from discussions here in general. I voted for Bush four years ago, but will be voting for Obama this time around.
