Gravis Marketing released its poll of Florida Republicans this week, which finds Bush ahead with 23 percent but Walker right on his heels with 22 percent. U.S. Sen. Marco Rubio, R-Fla., places third with 11 percent followed by former Gov. Mike Huckabee, R-Ark., with 10 percent. Huckabee moved to Florida after his 2008 presidential bid. My prediction is that Rubio will be an early dropout. If he can't read that handwriting on the wall, it won't matter.
