Nonsense. Santorum is 2nd choice of Bachmann, Newt, and Perry’s voters. He would be well ahead of Romney if Newt drops out, and that may become the scenario that should happen.
Huckabee didn’t do well after Iowa last time. Santorum is this year’s Huckabee, the choice of religious conservatives, particularly those ones who don’t think for themselves and just do what their preacher tells them to, and no one else. And this year religious conservatives will be driving the primary even less than they did last time. Romney will defeat Santorum in the vast majority of states on perceived competence alone.
