Gov. Chris Christie (R-N.J.) said Monday that Mitt Romney might be able to persuade him to accept the No. 2 slot on the GOP presidential ticket.

Christie, who has repeatedly said he isn't interested in being the vice president, said if the presumptive nominee called and asked him to consider the post, he would listen.

"He might be able to convince me. He's a convincing guy," Christie told an AP History class in Plainsboro, N.J., according to the Philadelphia Inquirer's Matt Katz.

Christie said it was highly unlikely he would be the best person for a job that involves playing backup. He jokingly asked the class whether they could see him sitting behind the president at the State of the Union, clapping and not talking.

"I like Gov. Romney a lot. I was one of his earliest supporters. I worked really hard for him to get the nomination and I'm thrilled that he's got it and I hope he's elected president," Christie said. "But being V.P. is a whole different story."

Christie said unlike the election Romney faces in November, the selection of the vice presidential nominee will come down to Romney alone.

"It's an election that has only one voter — and that's him," Christie said.

This is the second time this cycle that Christie has faced repeated questions about his higher ambitions. Republicans eagerly courted Christie to run for president, and although he considered it briefly, he eventually opted against a run in 2012.
