Funny poll result

Here's a curiosity. According to this week's CBS/New York Times poll, "support for the initial invasion of Iraq has risen somewhat as the White House has continued to ask the public to reserve judgment about the war until at least the fall.

What?

Specifically, support for the invasion was at an all-time low in May, at 35 percent, but in the poll taken over this past weekend, 42 percent of Americans say they support the initial invasion. 51 percent say the U.S. should have stayed out, while 61 percent said so in May. The number of people who say the war is going "very badly" has fallen from 45 percent in June to 35 percent now.

This makes no sense. At least not logically. I can understand a lower percentage saying the war is going very badly now; there have been stories of tribal leaders deciding to oppose al-Qaida and all. But why should that fact change your perception of whether we should have gone in in the first place? If you really think it was a bad idea, the fact that it isn't going as badly as a few weeks or months ago shouldn't change that judgment. Should it?

It's enough to make you think Bryan Caplan has something with his "Myth of the Rational Voter."
