Chris Christie: I’d "Answer The Call" If Asked To Be Vice President

"This is an election with one voter, Mitt Romney. He gets to decide who he thinks should be the vice president of the United States," New Jersey Gov. Chris Christie (R) said in a CNBC appearance Tuesday. "I love being governor of New Jersey, you can tell. But the fact is, if Gov. Romney picks up the phone and calls, you have to answer the call and listen at least," Christie said on CNBC's "Squawk Box" this morning.
