Longtime Democratic state Sen. Bob Jauch, of Poplar, will retire and not seek re-election next year.
Jauch announced his intentions at a news conference Wednesday in the state Capitol. The 67-year-old Jauch was first elected to the Senate in 1986 after serving four years in the Assembly.
"Virtually for every day for my last 31 years I have dedicated 1,000 percent of my heart and soul to northern Wisconsin and fight for the issues that matter to them," Jauch said. "I love that district."
Jauch's Senate district covers the northwestern corner of the state along the Minnesota border and along the shores of Lake Superior.
Jauch was one of the 14 Senate Democrats who fled the state in 2011 in an effort to block passage of Republican Gov. Scott Walker's proposal effectively ending collective bargaining for public workers. More recently, Jauch has been an outspoken critic of the bill making it easier to open an iron ore mine in his district in the Penokee Hills.
He did not say what he plans to do with his future outside the Senate.
