Priorities USA is a super PAC supporting President Obama. Here's the group's latest ad, "We The People."

What it says: "Mitt Romney's budget plan will hurt the middle class, raising taxes on the average family by up to $2,000, while giving a tax break of $250,000 to multimillionaires."

What it means: Romney's policies are not middle-class friendly. Don't vote for him unless you want tax breaks for the wealthy at the expense of ordinary Americans.

Who will see it: Voters in Colorado, Florida, Iowa, Ohio, Virginia and Wisconsin.
