Obama for America is airing a new ad in Florida and other swing states during the Opening Ceremony of the Olympic Games, titled “I Believe.” The positive spot makes no mention of Mitt Romney – it uses a 30-second clip from a recent Obama speech.

“We’re a nation of workers and doers and dreamers,” the president says in the video, from a July 14 rally in Hampton, VA. “We work hard for what we get. And all we ask for is that our hard work pays off. I believe that the way you grow the economy is from the middle out. I believe in fighting for the middle class because if they’re prospering all of us will prosper. That’s the idea of America and that’s why America is the greatest nation on earth.”
