While I am sick to death of these debates, what will really be interesting in this one is how many questions will Santorum get compared to the others? Will CNN try and marginalize him?
If the last ones are any indicator, and matched with the polls, I foresee: Romney getting the majority of the air time, Santorum having to field mostly gotcha questions, Paul getting some questions to make us all look loony, and Gingrich getting a couple yes/no questions.
Santorum will be asked about contraception.
