No, I am not endorsing. Rather, I noticed that Palin has decided to start running for the GOP nomination for president now. She is actively disagreeing with John McCain on Gay Marriage and overall campaign tactics. John Edwards vented his strategy disagreement more quietly--as a source in a news story for instance--while Palin is happy voice her suggested alternatives to the media while the cameras are "rolling" so to speak.
It is almost as if she positioning herself to run next time already, believing McCain will lose badly. But I don't think GOP primary voters are dumb enough to nominate her.
