In Florida, hundreds of people remained in line waiting to cast ballots at some locations even as polls closed — at 7 p.m. in most of the state, 8 p.m. in the western Panhandle counties.
Under state law, anyone already in line when the polls closed will be permitted to vote.
Shortly before polls closed in Virginia, meanwhile, the Obama campaign sent out text messages saying that volunteers were needed "right now" to make sure that everyone who was still in line as polls closed got to vote.
The text asked recipients to reply, and said an organizer would call as soon as possible with further instructions.
The campaign did not respond within 30 minutes to a text sent by a reporter.
