Its both parties. Both parties are continuing their slide to the extremes. I blame the media cause they all push things to the extremes. I mean look at Delaware they framed Castle as being a rino when if you look at his actual numbers he voted with the republicans in the 70s-80s... Does that mean my Rep Shelley Moore Capito risks getting side swipped cause she has scores in the 60s from the AFL-CIO (and vote with the majority of Republicans in the 80s during Bush) in a state that is largely pro-union and she's a free trader? If thats the case I want NOTHING to do with Sarah Palin and Jim DeMint. Its why we have so much deadlock we gotten a majority of the extreme as rep and the few more moderates are afraid of saying something because theyre afraid of getting lambasted by the wings and getting a challenger who wins because most people stay home.
