Hey, it worked for Hillary!
Well, that didn't take long. Mitt Romney became the first "copycat sobster" yesterday when he "choked up" at a rally in Michigan. From today's NY Times:
Earlier in the day, after hearing from a voter who recalled his father, Mr. Romney choked up momentarily, according to a pool reporter who was present. “He was a great man, and I miss him dearly,” Mr. Romney said.
Anyone care to place bets on who will be next?
