According to poll-guru Nate Silver, "Romney has made larger-than-average gains in (Florida) since the Denver debate, and has now become a definitive favorite there."
Silver says Romney has a 69 percent chance of winning the state, and Obama is better off spending his limited resources in other swing states, like Ohio, Nevada and Iowa.
Obama won Florida narrowly in 2008, but along with North Carolina is one of the most Republican-leaning swing states.
