"I think the tone of the campaign on our side's been good. We've been talking about the vision for Wisconsin's future," Evers said.
"Walker has decided to sink to a new low, but we expected that," Evers added.
In a statement, Walker's campaign spokesperson Austin Altenburg said Evers was spreading false information.
"The false attacks coming from Tony Evers and his big government special interests are increasing as they desperately try to distort Scott Walker's strong record of reform," the Governor's campaign said.
"While Evers attacks, Scott Walker will continue offering a vision for the future," Altenburg said.
The Governor's campaign said the plan would result in the release of violent criminals.
"A dangerous plan that today would mean releasing thousands of violent criminals back into our communities, which could include felons who committed rape, assault, robbery and even kidnapping," the ad spot says.
Evers said that's not true.
"This isn't about releasing violent people to prey on Wisconsin," Evers said. "This is about doing the right thing for people who are not violent."
"We will not release violent criminals," Evers said. "We need to have a correctional system that's focused on rehab."
