Revising to:
Paul 27%
Romney 24%
Santorum 20%
Gingrich 10%
Perry 10%
Bachmann 6%
Huntsman 3%
Staying here, not convinced Santorum's momentum will persist and the socons/Gingrich continue to split the endorsements. Could see Paul/Romney lower and the socons higher, but that's mainly a question of turnout.
Final predict.
Paul 25%
Santorum 22%
Romney 20%
Gingrich 13%
Perry 12%
Bachmann 6%
Huntsman 2%
Santorum surge is real but still doesn't seem consensus. Perry and Gingrich have stabilized and have their strong supporters. Paul will get his loyalists out. Romney is a favorite but not enough to inspire caucus-goers. Bachmann fades, Huntsman pisses away what little support he had with snobbery.
May be a little wishful thinking in there. Any of Paul, Santorum, Romney can win, it will hinge on Santorum loyalty and Romney inspiration.
