Mitt Romney was not "weak" in tonight's debate but he didn't really shine either. In fact the candidate that really seemed to stand out as a forceful and thoughtful proponent was Mike Huckabee, perhaps an indication of why he's surging in many polls.
Huckabee appeared the most poised as he addressed issues like religion and the death penalty.
As candidates often do, Romney carefully parses many answers carefully to avoid damaging sound bites. His exchange with McCain over torture and waterboarding left one wondering if Romney is willing to take a strong stand, though his abortion statements seemed to please the crowd when he said he was wrong to be pro-choice early in his career and is now emphatically pro-life.
