Let's list the ways this pastor is screwing up:
1) He's preaching politics from the pulpit (the fact that he says he isn't doesn't make it true)
2) He's using his position as a religious leader to harp on his own personal issues
3) Christians as a rule are expressly not allowed to hate anyone. Especially when they call themselves Christian leaders.
4) Even if God is real, what makes this guy think God shares his opinion? When Bush got elected, the Christian right said it was a mandate from God. How can it suddenly be the power of Satan that got Obama to the same office?
5) He's a moron, and now he's a moron who got his name on the Secret Service's list. I'm sure that will work out well.
