Polls shut in too-close-to-call Florida, 15 other states

WASHINGTON (AFP) - Polls closed on Tuesday in 16 states including the populous states of Pennsylvania and Florida, where networks said the race between President Barack Obama and Mitt Romney was too close to call.

Florida, with 29 electoral votes in a contest where 270 are needed to win, is the largest US state considered competitive for both candidates. Mr Romney made a late campaign push in Pennsylvania, where polls have shown Mr Obama to be ahead.

Polls also closed at 8.00 pm (1am GMT, 9am Singapore time) in battleground New Hampshire as well as Alabama, Connecticut, Delaware, Illinois, Maine, Maryland, Massachusetts, Mississippi, Missouri, New Jersey, Oklahoma, Rhode Island, Tennessee and Washington, DC.
