You know...
Obama's campaign is running like hell from this entire subject. They know the differences, both in what is being said, and the level of involvement with the preachers by the candidates. So do you.
BTW, the examples you've been using pretty much nail down the second/third/fourth hand sources you've been using. You might want to do a bit of your own research (for a frigging change).
Start with looking up an actual preacher calling for prayers for the "death of Supreme Court justices."
I know Pat Robertson had something on God getting justices to retire. You have something I don't? Bring it.
