Republican Gov. Scott Walker and Democratic challenger Mary Burke are set to campaign across Wisconsin, exactly 17 weeks before the Nov. 4 election.
Burke plans to tour a hops farm in Mazomanie and the Potosi Brewing Co. Tuesday before heading west to the Food Enterprise Center in Viroqua.
Meanwhile, Walker plans to tour a powder coating plant in Oregon, south of Madison, and a specialty wristband manufacturer in New Berlin.
The events come five weeks before the Aug. 12 primary. Walker is unchallenged while Burke is being taken on by state Rep. Brett Hulsey.
He is mounting a longshot campaign against the better-funded Burke, who is a former state Commerce secretary and Trek Bicycle Corp. executive.
