The spot will be aired in "key states," according to the campaign.
It opens with video of Obama telling Joe "The Plumber" Wurzelbacher that "when you spread the wealth around it's good for everybody." The spot then shows three women saying directly to the camera, "I'm Joe The Plumber."
"Spread the wealth?" an announcer asks, incredulous.
"I'm supposed to work harder," one man says, before another finishes the thought, "Just to pay more taxes?" A third man then says, "Obama wants my sweat to pay for his trillion dollars in new spending?"
After another woman identifies herself as Joe The Plumber, the announcer concludes: "Barack Obama. Higher Taxes. More Spending. Not Ready."
