OBAMA VS ROMNEY ...KNOCKOUT BLOW!

President Obama will try to pull himself — and his campaign — off the mat tonight AFTER THAT ASS KICKING!  when he debates rival Mitt Romney again, this time at Hofstra University in Hempstead, L.I.

Obama got his bell rung hard during their first debate in Denver — and he knows that another defeat could be devastating.

“It’s as important as a Game 7 in the World Series even though there’s a third debate,” Democratic strategist Chris Lehane said. “The pressure will be on the President to step up to the plate and deliver.”
