The ad, "Heavy Load": 

What it says: “The 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.”

What it means: A vote for Romney is not a vote for the middle class. 

Who will see it: Voters in Colorado, Iowa, New Hampshire, Nevada, Ohio, Virginia, and Florida.
