there you have one candidate calling him tweddle dumb. it does, i have seen these candidates over the last few days on tv and they look tired. things are tired to evolve in the way you re talking about. but santorum, the name calling is that he is trying to make a point. he says they re like match set, they re twins, and the point is an ideological point. and he s trying to say that the problem with romney is that he is too close to the president on some issues, and the party would do better with starker and clear i contracts and santorum believes he would be that candidate. more conservative than romney and able to draw differences on key issues like health care and several others.
