On the eve of the 2012 Democratic National Convention kick-off and just in time for Labor Day, President Obama’s re-election campaign has released a new TV ad that says Mitt Romney’s plan will increase the already “heavy load” being born by the American middle class, while giving the rich a break.

Expect to hear a whole lot more of this “he’s rich and out of touch with real working class people” theme as the convention gets underway. The script:

“he middle class is carrying a heavy load in America. But Mitt Romney doesn’t see it.”

“Under the Romney plan, a middle class family will pay an average of up to $2,000 more a year in taxes. While at the same time giving multi-millionaires like himself a $250,000 tax cut.”

“So, Romney hits the middle class harder, and gives millionaires an even bigger break. Is that the way forward for America?”

The ad will air in Colorado, Iowa, New Hampshire, Nevada, Ohio, Virginia, and Florida. (Not North Carolina).
