Obama campaign touts 'middle class' in Olympics-timed ad

"We're a nation of workers and doers and dreamers. 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," says Obama in the ad.

The 30-second spot is set to air during the Opening Ceremony of the 2012 Olympic Games. The ad features Obama delivering a speech, mixed in with video images of office workers, farmers and families.

"President Obama believes the only way to create an economy built to last is to build it from the middle out — where hard work pays off, responsibility is rewarded, and everyone gets a fair shot. And that’s why he will continue to fight for the middle class, because America prospers when everyone succeeds," said a text statement released with the ad.

The Romney campaign has been hammering the president for his controversial "you didn’t build that" remark made earlier this month, accusing Obama of mishandling the economic recovery by favoring government over individual success and entrepreneurship.

“Throughout his time in office, President Obama has consistently sided with government, not business owners, when it comes to the economy. But the disappointing results speak for themselves: middle-class Americans are still struggling, and job creators still aren’t hiring. It’s clear President Obama just wasn’t up to the task of fixing our economy," said Romney spokeswoman Amanda Henneberg in a statement Thursday.
