FILE - In this Sept. 26, 2012 file photo, President Barack Obama pounds fists with a supporter after speaking at Kent State University in Kent, Ohio. Mitt Romney’s campaign is working hard to chip away at President Barack Obama’s advantage among early voters, and there are signs the effort is paying off in North Carolina and Florida, two competitive states that the Republican nominee can ill afford to lose. Obama is doing better in Iowa, another battleground state important to both candidates. (AP Photo/Tony Dejak, File)
