At a Denver rally Thursday morning President Obama reflected on his opponent's performance in last night's debate. "When I got on to the stage, I met this very spirited fellow who claimed to be Mitt Romney. The man on stage last night does not want to be held accountable for the real Mitt Romney's decisions...for the last year," Obama said. "So Governor Romney may dance around his positions, but if you want to be president, you owe the American people the truth...So here's the truth: Governor Romney cannot pay for his $5 trillion tax plan" without inflating the deficit or harming the middle class. He also mocked Romney for his Sesame Street reference. "Thank goodness somebody is finally getting tough on Big Bird," Obama joked.
