Milwaukee businessman Andy Gronik has formally launched his campaign for guv, declaring on a new website that it’s “time for a different kind of leadership in Madison.”

Gronik also used the website to take a shot at Gov. Scott Walker, saying the days of the incumbent blaming “the people of Wisconsin for the fact that his policies can’t grow our state are coming to an end.” He also wrote Walker will undoubtedly have unlimited resources, “but I am not intimidated.”

“I’m not a politician. I’m a business leader with the progressive values necessary to beat Governor Scott Walker and make living in Wisconsin better for all of our residents — that’s why I’m running for governor,” Gronik wrote.

Gronik did not immediately respond to an email from WisPolitics.com seeking comment after he announced his campaign in an interview with The Associated Press.

The state GOP, meanwhile, slammed Gronik for issues that popped up while he was considering a bid. That includes questions about an attorney who worked with the Stage W group Gronik created and paying for a poll that referred to state residents as “Wisconsonians.”

“While Governor Walker has offered real reforms and proven results for Wisconsin’s working families, out-of-touch con artist Andy Gronik has offered only far-left fantasies and shady political behavior,” said state GOP spokesman Alec Zimmerman.

The party plans to launch a digital campaign hitting Gronik, the first significant Dem candidate to jump into the guv’s race.
