ABC News -- In the wake of Tuesdays vote democrats have made hay of a GOP civil war but all is not well on their side either. Move-On and Democracy of America are putting up $3.5 million to fund primary challenges against any Democratic Senator who blocks an up or down vote on the public option. Liberal democrats have been at war with centrist democrats throughout the health care debate. Remember this ad against Nebraskas Ben Nelson: That drew rebukes from several senators including Chuck Schumer. Will those same senators tell Move-on to stand down too? Or, at the end of the day will any democrat block a vote on the public option?
