However, Obama may cry crocodile tears over being thwarted. If he thinks Hillary will be the next President, he may angle to be her nominee. If he thinks that is how things will play out, he might even drag his feet, a bit.
I think Obama wants to get out of town and climb on the gravy train. There are people who think Obama wants to remain President or go to the Supreme Court. I think the opposite.
The only President in my lifetime that appeared that he wanted to stay was Clinton. The rest of them looked they they could not wait to disappear.
I could see them nominating Hillary, and bringing Biden out of the barn.
