Obama's got his preacher problem, McCain's got multiple preacher problems, and I'm sure the fact that Hillary doesn't have one yet is probably because she doesn't really go to church much. I was going to say something about how this is the sort of problem that's going to keep coming up as long as we refuse to elect atheists, but now that I think about it, I guess the path that the Clintons and the Bushes and, in fact, most of the office holders in this country have taken is the way to go. Say you're religious, but be vague on the details and try to spread your church attendance around, if you go at all.
Obama, who seems to authentically have a faith, and McCain, who has to provide bona fides to the religious right, are both now getting bitten in the ass by the particulars of their faith. Like a lot of things, faith looks best from a distance, with a good bit of vaseline on the lens.
Note: I should add that I think there's a serious gap between Obama's pastor holding offensive views and saying offensive things and Obama being blamed for them. He's been asked, he said he strongly disagrees with his pastor, and I think that's enough. McCain, on the other hand, continues to keep his lips firmly planted on the butts of a couple of pastors who believe some truly repulsive (and sometimes laughable) things.
Update: As usual, I spoke too soon. Now Hillary's got a preacher problem, too.
