Sunday's Republican debate in New Hampshire was awkward well before the on-stage spats began.
The trouble began, Politico relates, during the candidate introductions to the ABC News event.
As New Jersey Governor Chris Christie walked out on stage, moderators David Muir and Martha Raddatz called out Dr. Ben Carson. A camera backstage showed Carson starting to walk out, but he stopped himself once he heard the moderators announce the next candidate, Ted Cruz.
