He's a putz. I hope that the democrats that he jumped ship for dont vote for him in the next election. Since if he can turn his back on the republicans like he did, he could do it again against the democrats if it suits his needs. Kind of sounds like he studied at the Machiavelli School of Politics. (that's not a real school...Machiavelli is the guy who said "the end justifies the means".)

Nebraska had a republican senator who voted pretty much demorepublicrat. (Chuck Hagel) I think he retired from politics so he didnt bother jumping ship.

I dont trust any politician from any party that can just switch party affiliations like that.
