Half an hour into this debate, Romney is shining as the most polished candidate with the smartest, most well-considered answers. He looks like the adult in the room. Gingrich, a super-smart guy, doesn’t have enough time to vent his brain on each question. Bachmann has risen to be the more formidable Romney alternative. Her answers are well-spoken and to the point. If you are Pawlenty or Santorum, you’ve got to be feeling left out right now. They are missing their opportunities, as is Herman Cain, the breakout star of the South Carolina debate.
