Garden State voters have since soured on the governor. Sixty-one percent of voters, including 40 percent of Republicans, say he should drop out of the race, according to a Nov. 10 Quinnipiac University poll.
An October Rutgers-Eagleton poll found similar results, with 67 percent of Garden State voters saying Christie should end his campaign.
His campaign had just $1.4 million in the bank as of Sept. 30, according to filings with the Federal Election Commission.
Christie was also asked about GOP front-runner Donald Trump's remarks in Iowa Thursday. "How stupid are the people of Iowa?" Trump said at a rally there, bewildered by Ben Carson's surge in the early-nominating state.
