Wisconsin's 24th Senate district

Patrick Testin is the senator representing the 24th district, and is the current President pro tempore of the Wisconsin Senate. He was first elected in the 2016 general election and is now in his second four-year term.^[3]

Each Wisconsin State Senate district is composed of three Wisconsin State Assembly districts. The 24th Senate district comprises the 70th, 71st, and 72nd Assembly districts. The current representatives of those districts are:

• Assembly District 70: Nancy VanderMeer (R–Tomah)^[4]
• Assembly District 71: Katrina Shankland (D–Stevens Point)^[5]
• Assembly District 72: Scott Krug (R–Rome)^[6]

The 24th Senate district crosses two congressional districts. The portion of the district in eastern Jackson County, northeast Monroe County, northern Juneau County, and western Wood County fall within Wisconsin's 7th congressional district, which is represented by U.S. Representative Tom Tiffany; the remainder of the district fall within Wisconsin's 3rd congressional district, which is represented by U.S. Representative Derrick Van Orden.^[7]
