Since the Republicans will surely hammer Obama's departure from Trinity Church all the way to November, perhaps it's appropriate for Democrats to begin asking why John McCain left the Episcopal Church for the Baptist Church, which is obviously on the opposite end of the Christian spectrum.

If McCain's rationale for changing denominations was theological rather than merely political as many suspect, perhaps he needs to explain his theological differences with the denomination that nurtured him for far longer than Obama spent at Trinity. After all, this is a much bigger change than simply leaving a particular parish family. That kind of questioning is fair game in Karl Rove's brave new America, right?

I don't like it, and won't ask it, but when politics increasingly coopts religion, it comes with the territory.
