Looks like Christie is leaving the VP door slightly open.

Christie says contested GOP convention is possible

Associated Press

WASHINGTON (AP) — 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."
