From political number cruncher Nate Silver on his 538 blog:

The Republican candidate, Rick Scott, has gained ground in Florida. The polling had been mixed there — but each of the five polls released in the past week give Mr. Scott a small advantage over the Democrat, Alex Sink. The model assigns Mr. Scott a 60 percent chance of winning, after he was a slight underdog in last week’s forecast; it is plausible that Mr. Scott has been assisted by the Senate race in the state, where the Republican, Marco Rubio, has run a strong campaign and has emerged with a clear lead over two opponents.
