New Jersey Gov. Chris Christie isn't ruling out the possibility the topsy-turvy GOP presidential race ends up in a contested party convention this summer if Mitt Romney loses Tuesday's Michigan primary.
Christie, who's endorsed Romney, says he thinks Romney will beat Rick Santorum _ and that would lessen chances of a convention fight.
But Christie notes the race has had several different front-runners and probably will keep going up and down.
He tells CBS' "Face the Nation" that "we have to be patient and take a deep breath and let this process work its way out."
The governor says he's not really interested in being a vice presidential candidate, but would listen if Romney asked because "I love my party enough and I love my country enough to listen."
