With the Florida Republican primary tomorrow, Mitt Romney appears to be finishing strong in the state. The polls show his support increasing modestly, and many of the polls now have him with a double digit lead over Newt Gingrich.

The Marist/NBC poll from yesterday found Romney with a 15 point lead: Romney 42 percent, Gingrich 27 percent, Rick Santorum 16 percent and Ron Paul 11 percent.

Similarly Quinnipiac now has Romney with a 14 point lead in the sate. This is a five point improvement for Romney from their polling only a few days earlier. From Quinnipiac:

Former Massachusetts Gov. Mitt Romney has a 43 – 29 percent lead over former House Speaker Newt Gingrich among Republican likely voters in Florida, the nation’s first big-state presidential primary, according to Quinnipiac University poll released today. Only 7 percent are undecided, but 24 percent say they might change their mind by tomorrow’s election

This compares to a 38 – 29 percent Romney lead in a January 27 survey by the independent Quinnipiac (KWIN-uh-pe-ack) University. [...]

Texas U.S. Rep. Ron Paul and former Pennsylvania Sen. Rick Santorum each have 11 percent of likely primary voters today.

Last night PPP found Romney with a smaller lead of just seven points, Romney 39 percent to Gingrich 32 percent, but that is a significant improvement for Romney from just seven days ago when PPP had him losing to Gingrich by five.

The polling is unanimous that Romney holds a substantial lead in the Florida primary. The polls differ only on whether Romney’s lead is in high single digits or in the low double digits.

There is a good chance tomorrow that the state will be called fairly quickly after the polls close.
