It's been a fight to the finish for President Barack Obama and Republican presidential nominee Mitt Romney.

From the early days of the New Hampshire Primary, Romney has been making the rounds through New Hampshire, while Obama joined him in the summer. In the past several weeks, it's been like a game of ping pong with visits to the state from the candidates, their wives, Vice President Joe Biden and his wife Jill, Paul Ryan and their surrogates.

Romney's final stop in New Hampshire was Monday night at the Verizon Wireless Arena with Kid Rock, while Obama visited downtown Concord on Sunday with past President Bill Clinton, drawing a record 14,000-person crowd in for a single campaign event in New Hampshire.

All that stands between them and the next four years is today's election. Take a look back at some of their moments in New Hampshire.
