The poll I found the most telling in terms of the recent trend in Florida is the last two Insider Advantage (IA) Florida polls. In a 1/22 poll, IA's poll had Gingrich leading Romney 34-26. In a poll conducted on 1/25, IA shows Romney leading 40-32. While Gingrich only lost 2 points on his total, Romney gained 14 points. Santorum and Paul were down 3 and 4 points respectively in the poll. The remaining 5 point increase in Romney's numbers were undecideds breaking his way as the January 31st primary draws near.
Gingrich has a week to turn things around. If he fails, Romney will have resurrected a campaign that was beginning to flounder.
