In New Hampshire, Christie's poll numbers have been surging, and he has become the only real threat to Trump in the race.

Christie was recently endorsed by New Hampshire's largest newspaper.

Trump attacked the newspaper and Christie by saying the Governor is destroying New Jersey and has no chance of winning.
