Following the excitement of the Iowa Caucuses, all eyes are now on New Hampshire, which will host the nation's first primary on Tuesday.

Tonight, all of the major contenders from both parties will be in the Granite State to take part in the New Hampshire Debates, presented by Facebook, ABC News and WMUR.

The Republican candidates will square off at 7pm/6c, followed by the Democratic candidates about 90 minutes later. Charles Gibson will moderate both debates.
