(CNN) -- There is a lot of buzz about CNN's new poll that shows Rick Perry seemingly solidifying his lead among Republican in the primary contest. Forty-two percent of Republicans think Rick Perry has the best shot at beating Barack Obama. Forty-five percent of seniors support Perry compared to 21% for Mitt Romney.

There is one question that is not getting as much attention, though in my mind it explains every other question. CNN asked, "Which Republican candidate is most likely to fight for their beliefs?" The winner? Rick Perry with 29%, followed by Sarah Palin at 23%. Mitt Romney? Michele Bachmann? They tied at 11%.

The answer to the question really says very little about Rick Perry and a great deal about Mitt Romney. It plays into the "opportunist" critique that many primary voters have of Romney.
