"I'm extraordinarily disappointed," he added. "I put a lot of time and effort into the Mitt Romney campaign from last October when I went to New Hampshire until my last trip for him the Friday before the storm when I went to North Carolina."
Christie, 50, commended the president for having "a very good night last night," and said he would email his condolences to Romney on Wednesday. "He knows I am sorry it didn't work out," Christie said. "I've lost elections. I know how it feels. It hurts."
Christie said he hopes Romney continues to be a voice in American politics. He said he expects the country's 30 or so Republican governors to be the party's "idea leaders" in the years ahead, but declined to predict whether Obama's second term will see a lessening of partisan gridlock in Washington.
"The president's got decisions to make about how to conduct himself and how he'll lead," Christie said. "I hope he'll do it differently than he did it the first four years."
