A leading group opposing Minnesota Democrats has launched its first television advertisement attacking DFL Gov. Mark Dayton and the state's health insurance exchange.

The 30-second ad ties President Obama's health insurance overhaul with the troubled launch of the state's health insurance exchange, MNsure.

"Barack Obama and Mark Dayton promised Minnesotans that Obamacare would help make things better," said Ben Golnik, chairman of the Minnesota Jobs Coalition. "MNsure remains a mess defined by missed goals, lost policies and bonuses for executives who failed in their jobs. Dayton is so out of touch with Minnesotans he even claimed Obamacare was working 'phenomenally well.'"

Dayton's campaign dismissed the ad as misleading.

"The reality is that today more Minnesotans than ever have access to quality healthcare at the lowest rates in the nation – with MNsure reducing the number of uninsured Minnesotans by 40 percent in its first year," said Dayton campaign manager Katharine Tinucci, citing a new University of Minnesota study.

The ad is part of a larger strategy in which Republicans nationally are blasting Democrats over the health insurance overhaul. Democrats are starting to punch back hard with stories of Americans who have been helped by the program. They are also highlighting that Republicans have not unveiled an alternative.

"This is a reminder of the Republican approach that would bring Minnesotans back to the days of out of control healthcare costs, discrimination against preexisting conditions, and lack of coverage for basic services like mammograms," Tinucci said.

Golnik said they will spend somewhere around $50,000 to run the ad statewide on cable and digital broadcast. That is generally not enough money to give the ad significant statewide reach.

The head of Alliance for a Better Minnesota, the main outside group attacking Republicans, would not say when they will launch their first ad.

"When it's strategically smart" said Carrie Lucking, executive director of Alliance for a Better Minnesota.

She also jabbed Golnik's group, however, saying that the group would not run "an ad attacking Obamacare the day after we learn that it's reduced our uninsured rate by 40 percent."
