According to the article, this poll was conducted on Sunday evening, while all the other polls were conducted through Saturday at the latest.
This poll would be the first to reflect any bump from the Cain endorsement and Sarah Palin’s comments last night.
But you’re right, we need to see a trend.
Although isn’t the number early voted in FL around 40% or so (I remember it was close to 20 two weeks ago) ? If Gingrich can close it with a late surge he will have momentum for sure but a win outright unfortunately almost seems a mathematical impossibility at some point.
