President Obama and Mitt Romney are on a final sprint through the battleground states.
The race is too close to call and the candidates know every vote counts.
Mitt Romney rallied supporters in Cleveland, Ohio--just one of four battleground states the Republican nominee is visiting Sunday.
The race could come down to a single swing state and both candidates are hitting as many as they can before election day.
President Obama even took time to join President Clinton in New Hampshire which only carries 4 of the 270 electoral votes needed to win.
Both the Romney and Obama campaigns are predicting victory on Tuesday, but the polls show a very tight race with no clear favorite.
Both candidates will continue their break neck pace on Monday, criss crossing the country during the final hours of the campaign.
More than 27 million Americans have already voted in 34 states and Washington, D.C. where early voting is allowed.
