The third and final Presidential debate ended in dramatic fashion tonight as President Obama punched Republican nominee Mitt Romney in the face, knocking him unconscious before a national television audience. As Mr. Romney lay motionless on the floor at Lynn University with 35:06 remaining in regulation, moderator Bob Schieffer declared the debate over, calling Mr. Obamas punch a clean shot. The Presidents uncharacteristic explosion of anger came after Mr. Romney repeatedly needled him about going on a global apology tour on behalf of the U.S. As the former Massachusetts Governor continued his harangue, TV viewers witnessed Mr. Obama glaring at his Republican opponent, a vein visibly throbbing on the Presidents forehead. Still, few observers were prepared for the sight of Mr. Obama leaping across the table and cold-cocking Mr. Romney, dropping him to the floor. Moments later, Vice-President Joe Biden jumped onstage to congratulate Mr. Obama with a jubilant high-five. You literally cleaned his clock, Mr. Biden said. I only wish Id done the same thing to that punk Ryan. After the debate, the usually mild-mannered Obama was at pains to explain why exactly he had struck Mr. Romney in the face: I guess I just couldnt take it any more, and I sort of snapped. It wasnt optimal. But he was being such a dick. Minutes after Mr. Romney was carried out on a stretcher, the debate was declared a victory for Mr. Obama by all the major networks except Fox News, who called it a draw.
