Newt Gingrich says he has no doubts that the Republican presidential candidates who fall short of winning the nomination will unite behind the eventual nominee - despite the often tough rhetoric the contenders are throwing at each other during the campaign.
Gingrich says "people shouldn't be at all confused about that" and that the GOP's goal is to deny President Barack Obama a second term.
He tells NBC's "Meet the Press" that Obama's re-election would be "such a disaster to the future of this country" that all the Republicans in the presidential race will "come firmly behind" the eventual nominee.
