The 11th Senate district of Wisconsin is one of 33 districts in the Wisconsin Senate.[1] Located in southern Wisconsin, the district comprises most of Walworth County, most of Kenosha County, and southwest Racine County, along with parts of southeast Rock County. It contains the cities of Burlington, Delavan, Elkhorn, and Lake Geneva, and the villages of Clinton, Darien, East Troy, Genoa City, Paddock Lake, Sharon, Union Grove, Walworth, along with most of the village of Pleasant Prairie and part of the city of Kenosha.[2]
Stephen Nass is the senator representing the 11th district. He was first elected in the 2014 general election, and is now serving in his second term. Before his election as senator, he was a member of the State Assembly from 1991 to 2015.[3]
Each Wisconsin State Senate district is composed of three State Assembly districts. The 11th Senate district comprises the 31st, 32nd, and 33rd Assembly districts. The current representatives of those districts are:[4]
The 11th Senate district is almost entirely contained within Wisconsin's 1st congressional district, which is represented by U.S. Representative Bryan Steil. The part of the district containing the northeast corner of Walworth County falls within Wisconsin's 5th congressional district, represented by Scott L. Fitzgerald.[5]
Note: the boundaries of districts have changed repeatedly over history. Previous politicians of a specific numbered district have represented a completely different geographic area, due to redistricting.
Previous senators from the district include:[6]
