What role is Mitt Romney's 1994 debate with Ted Kennedy going to play in next year's primary? Has Romney done enough to ease the doubts of social conservatives? What more does he need to do? Someone recently uploaded an edited segment of the 1994 debate onto Youtube and it's making waves on beltway political sites today. Will Romney be able to put the stances he took back them to rest once and for all? Moreover, who is responsible for stirring this pot again?
