Wisconsin 2026 elections: Republican Julie Helmer challenges freshman Democratic incumbent Karen DeSanto in 40th Assembly District

Prior to redistricting, the 40th Assembly District included parts of Waushara and Wautoma counties in a red area of the state.

The redrawn 40th has a completely new look.  It now incluces parts of Sauk and Columbia counties, including the cities of Portage, Baraboo, Prairie du Sac, and Sauk City.   The new 40th tends to lean Democratic.
