I’m not too worried about the poll showing McCain suddenly ahead of Clinton and Obama. The horserace polls are always somewhat complicated by (1) transient emotion and (2) strategic responding. I’m sure some of my fellow Obamistas are telling pollsters they’d vote for McCain. But my guess is that most of them are fibbing, and the rest will change their minds when they calm down. Same thing for Hillary’s voters. McCain is just getting now the boost the Democrat will get when the nomination is finally decided.
