I don't think Ohio actually went for Obama. He felt very exposed doing all that vote fraud, especially as it's being discovered now. He's mad. When he's mad at someone, he gets revenge. He hunts them down.

And that is why he has decided to punish Ohioans who "should" have voted for him, but did not with sufficient reliability. He was paying them good money for their support, and they didn't perform adequately on election day, causing him a lot of trouble and some risk.
