This is a bare-knuckled street brawler, afraid of no one, and showing no fear when it came to pursuing men of power. Christie has two weapons he can draw upon in the national campaign: He can make an eloquent case against the president, and humiliate him intellectually, or he can get into the gutter with Barack Obama, and kick the living shit out of him on the president's home turf (the "Mud Bowl", redux).
It's what Romney cannot do. So that, most likely, is why Chris Christie is in Israel today, sneering at Bashar al-Assad, while simultaneously staring down Hezbollah:
