New Jersey Gov. Chris Christie (R) on Tuesday declined to commit to serving another full term as governor if he is reelected next week. Christie was on "Good Morning America" on the first anniversary of Hurricane Sandy, but the topic of conversation also included Christie's potential 2016 presidential run -- a campaign that, were he to win, would require him to step down with a year left in his term. "I'm committed to being the best governor New Jersey can have for as long as I can possibly do it," Christie said. "But, you know, George, neither one of us have a crystal ball and know what's going to happen in the future." Christie has made little secret that he is interested in running for president in 2016, even as he has sought reelection to his current job. He is expected to defeat Democrat Barbara Buono next Tuesday by a wide margin. "I've been really honest with the people of New Jersey and told them exactly that," he said. "I'll do this job as long and as aggressively as I possibly can, and my current intention is to spend four years, but we'll see what happens, George, you never know what life's gonna bring you."
