Concord, N.H.

In today’s NBC debate, Newt Gingrich was able to land perhaps the most devastating blow on frontrunner Mitt Romney of the morning.

Rick Santorum had the assist, setting up the attack by criticizing the former governor of Massachusetts for refusing to run for reelection in 2006. “Well, if [Romney’s] record was so great as governor of Massachusetts then why didn’t he run for reelection?” Santorum said. “If [you] wouldn’t stand for the people of Massachusetts and run on your record, if it was that great, why did you bail out?”
