Arlen Specter, Senator from Pennsylvania, set to switch from Republican to Democrat. Like that is a real surprise? I am just surprised that he didn't do it sooner, he has been a RHINO (Republican in Name Only) for so long that sometimes it was hard to remember that there was that little "R" next to his name on CSPAN.
Edit: I have to be honest and say that if I thought this wasn't done for purely political reasons I wouldn't have as much disgust with the situation. But the PA polls were clearly showing that Spector would most likely have been beaten in the Republican primaries by Pat Toomey, the fellow that ran in the Republican primary against him last time (and almost unseated him). So his switch seems to be for political reasons only and that is just a sweaty, slimy mess of a thing to do.
