I'm calling it now.
Florida, with 81% of the vote counted has Obama ahead, and with the vast majority of the remaining uncounted votes in historically democratic counties, The Lone Bolt projects Obama takes Florida: 29 electoral college votes.
Pennsylvania has already been called for Obama. It also looks like he's taking NH.
Virginia and NC go to Romney. But of the remaining battleground states, based on the most recent polling Obama should take WI and IA. Ohio is still close but with Florida on Obama's side the Dems don't need it. Nonetheless I'm going to go out on a limb and say Obama takes Ohio too.
