The Democrats and their union allies have zeroed in on Ohio Republican Jim Renacci's tax troubles.
Renacci got entangled in a complicated dispute with the state of Ohio over whether his network of businesses, which includes nursing homes and an auto dealership, made a profit in 2000.
Renacci, who's running against freshman Rep. John Boccieri (D-Ohio), declared a loss on his taxes. But after getting audited, he and his wife ended up settling with the state for more than $1.3 million in back taxes, interest and penalties, court records show.
The Democratic Congressional Campaign Committee and the Service Employees International Union tried to unravel the issue in separate 30-second spots.
But it appears the union, whose ad was released first, may have done the better job.
