Matt Steinglass has sympathy for the birthers:
I remember having a general sense, during the 2004 presidential campaign, that I believed George W. Bush had probably skipped out on some of his Air National Guard duty during the Vietnam War. Then the "60 Minutes" documents turned out to have been pretty clearly faked, and I suspended that belief. And yet I still sort of think it might be true. Why is that? … [W]ith the source of the initial bits of information lost, because I've forgotten it, I'm left with this vague impression that this story could be true. Or false. But it's not incongruent with my worldview. Right now, if you asked me, I'd say I just don't know.
