Because the Repuglicans have no balls and no backbone. As well as MCconnell ges his litle henchman in there and threatens the Repuglican Senators with ‘if you go against me and obama, I will personally make sure you have no repuglican support and w will handpick a candidate and finance the candidate o run against you”. It is called extortion, which is a crime, but you know that the government never prosecutes the criminals that are in leadership they just go after the litl guy an people like Martha Stewart and someone whom they can trash!
Its NOT about political parties, its about POWER & PAY OFFS!!!
