TAMPA, Fla. (AP) - Florida is proving to be an expensive and frustrating state for President Barack Obama and Republican Mitt Romney, right down to the campaign's final minutes.

Its voters resist arguments that play well in Ohio and other places. Both nominees are making stops in Florida in the campaign's final 40 hours.

Florida is a tough sell for Obama's national message of steady economic recovery. Its unemployment and foreclosure rates remain above the national average.

And auto industry ads airing in Ohio would make no sense in Florida. But a well-organized Democratic ground game and a population that's increasingly non-white have given the president hope of winning Florida narrowly.

Romney had hoped to lock up Florida long ago.
