APOPKA, Fla. – President Barack Obama and Republican Mitt Romney have this in common when it comes to Florida: They’re both worried about the biggest election battleground prize.

The president has an edge here, but Democrats fear the advantage may be fleeting and fret about Florida’s undecided voters. They’re also nervous about legal battles over state voter laws that could cut into Obama’s support among minorities.

Republicans are concerned that Romney hasn’t closed the deal in a state hampered by joblessness and home foreclosures, even though he’s cast himself as the economic fixer and, along with his allies, has spent significant money and time here.
