Wisconsin's 31st Senate district

Jeff Smith is the senator representing the 31st district. He was first elected in 2018 general election. He previously served in the Wisconsin State Assembly from 2007 through 2011.^[3]

Each Wisconsin State Senate district is composed of three Wisconsin State Assembly districts. The 31st Senate district comprises the 91st, 92nd, and 93rd Assembly districts. The current representatives of those districts are:

• Assembly District 91: Jodi Emerson (D–Eau Claire)^[4]
• Assembly District 92: Treig Pronschinske (R–Mondovi)^[5]
• Assembly District 93: Warren Petryk (R–Washington)^[6]

The district is located almost entirely within Wisconsin's 3rd congressional district, which is represented by U.S. Representative Derrick Van Orden. The exception is one area of Chippewa County which falls within Wisconsin's 7th congressional district, represented by Tom Tiffany.^[7]
