Wisconsin Gov. Scott Walker stopped at Exodus Machines in Superior on Wednesday during the final leg of his re-election bid tour.

"I am more optimistic about the state than at any time in my life," he told the crowd, asking them for another four years in office.

Walker stressed workforce gains and tax savings in the state during his seven years of leadership.

"From one end of the state to the other, crisscrossing the state, we're seeing exciting things happening," Walker said. "We're moving Wisconsin forward. It's not just about jobs, it's not just about businesses."

He pointed out that tuition has been frozen at University of Wisconsin campuses and that more dollars were invested into K-12 education in the current state budget.

"I'm pleased to say not for one year, not for two years, but for six years in a row we've frozen tuition at all of our University of Wisconsin campuses for undergraduates here in this great state," Walker said.

He promised to drug-test welfare recipients.

"Public assistance should be more like a trampoline and less like a hammock," the governor said.

And Walker said the state needs to double-down on the fight against the opioid crisis and illegal drug abuse.

The governor was introduced by Exodus CEO Kevin Boreen. The Superior business, which engineers, manufactures, sells and services attachments for the recycling and demolition industry, employs 75.

The state was one of the first to the table to say "how can we help," Boreen said. Together with the city of Superior, Douglas County and other agencies, they put together a financing package that helped Exodus build its facility.

"That was in a large part because of the pro-business attitude of Gov. Scott Walker, so thank you for that," Boreen said.
