State Sen. Julie Lassa (D) has released a tough new ad calling into question Republican Sean Duffy’s success as a district attorney. Dan Goglin, assistant district attorney for Ashland County, is featured in the ad.

“We did not see him often. His campaign was taking him away from the job. All the time witnesses, victims would have to wait in the hallway for him to come to work. The quality of services that were provided to the citizens of this county suffered,” Goglin says in the 30-second spot. “Sean Duffy was a no-show.”

The toughness of the ad reflects a tight race to replace retiring Democratic Rep. David Obey. Both House campaign committees are also airing ads in the northwestern Wisconsin district.

The Duffy campaign noted he resigned from his job to focus on the campaign.

“Lassa’s latest ad with a Democratic operative talking negatively about Sean is an interesting attack from a career politician who only campaigns on taxpayer dollars, but we’d rather have Lassa hiding out in her campaign office than continuing her anti-job votes and big government spending record in Madison,” Duffy spokeswoman Wendy Riemann said.

This is Lassa’s fourth ad, and a Lassa spokeswoman said it is airing in the majority of the district. The commercial Duffy is airing compares his skills cutting lumber to the way he would cut spending in Washington.
