The pro-Republican super-PAC American Crossroads is up with a $9.3 million ad buy slamming President Obama's attacks on Mitt Romney's private-sector record as "unfair" and "untrue."
The group also argues Obama is attacking Romney because he can't defend his own record.
"What happened to Barack Obama?" the ad's narrator asks over footage of his Democratic National Convention speech in 2008. "The press and even Democrats say his attacks on Mitt Romney's business record are 'misleading, unfair and untrue,' 'blowing smoke,' 'too far,' 'no evidence.' So why is Obama attacking? He's added $4 billion in debt every single day. Unemployment stuck above 8 percent. Family incomes falling. Barack Obama can't run on that record."
The ad will air in nine states: Colorado, Florida, Iowa, Michigan, Nevada, New Hampshire, North Carolina, Ohio and Virginia.
It's notable that the ad is running in Michigan, a state where polls show Romney is close to taking that appears to be on the cusp of "swing state" status.
