CNN entrance polls show Ron Paul, Mitt Romney and Rick Santorum in the top tier of candidates. No surprises.
Entrance polls of those who arrived early: Paul and Romney lead with 24%, followed by Santorum at 18%, Gingrich at 13%, Perry at 11% and Bachmann at 7%.
One prediction I'll make: Entrance polls will seem way off from final results because caucus attendees can react to the data as it comes in on their phones.
Complete entrance polls -- early and late arrivals -- show Paul leading with 24%, Romney at 23%, Santorum at 23%, and Gingrich at 13%.
NBC News election models show first and second place within .3%. They also conclude entrance polls overestimated Paul's strength.
