UPDATE: Atrios suggests that those in attendance at the inauguration turn their backs on Rick Warren. Mahablog has some thoughts worth considering, as does digby. Will also link to Ruth when she gets her post done.
MORE UPDATES: Here's Ruth's post, and don't miss Greenwald's interview with Pam Spaulding. Steve Benen over at Washington Monthly posted Obama's response which, as he notes, sounds nice but is ultimately unpersuasive. Benen, however, says:
I'm reluctant to make too big a deal about this. As I argued this morning, it's a symbolic gesture, which will likely have no substantive effect whatsoever. But that doesn't change the fact that it's a mistake.and I'm inclined to disagree with that. I think it might be substantively damaging indeed. "The Left" as I see it, is tired of being marginalized.
