Republican Jeff Johnson hammered on the Dayton administration's handling of MNsure Friday, in what has swiftly become a principal theme of his campaign for governor.

It was Johnson's third press conference on MNsure since the news earlier this week that PreferredOne, which offered the lowest rates and sold the most plans on the state health insurance exchange in the last year, is pulling out. Four insurance companies continue to sell plans on the site, but Johnson and Republican allies seized on the news as they try to take advantage of the Dayton administration's struggles to get MNsure operating efficiently.

This time, Johnson called for Minnesota's legislative auditor, a Capitol watchdog agency, to expand an ongoing MNsure audit to include a look at the Dayton administration's role in setting PreferredOne rates. Johnson said the situation "looks fishy," but was not able to offer any evidence or even specific allegations of wrongdoing.

"That's what we need to find out," Johnson said.

A day earlier, Dayton when asked by reporters said his administration did not dictate anything to PreferredOne. The company has made no allegations to that affect, either.

"The Commerce Department and the administration do not dictate to these companies what the rates are," Dayton said. "The notion that we set these rates is another one of the fallacies that those who are opposed to the system want to perpetuate."

While Johnson has tried to turn the MNsure issue against Dayton, the DFL has hit back against Johnson by highlighting some of his own past votes on health care. Specifically, Johnson acknowledged Friday that as a state legislator in 2003, he voted for a budget backed by then-Gov. Tim Pawlenty, a fellow Republican, that eliminated about 38,000 adults without children from state-provided health care coverage.

"That was a decade ago in the midst of a very deep deficit that we were in the middle of and that was part of the governor's plan to balance the budget without tax increases," Johnson said.

Earlier in his campaign, Johnson talked more frequently of scrapping MNsure altogether. He still says he'd seek a federal waiver from complying with the federal Affordable Care Act, but has also acknowleged that if elected he would likely have to continue to deal with MNsure.

"We have MNsure sitting in front of us and we have to figure out how to move on from that," Johnson said.
