Wisconsin's August 9 primaries determine candidates for key races, including Senate and House seats, alongside constitutional amendments.

Wisconsin's state primaries on August 9 will determine candidates for key races, including the Republican challenger to Senator Tammy Baldwin. Primaries in two U.S. House districts could impact Congress's balance of power. The state legislature, currently Republican-controlled, will likely be reshaped in November after new legislative maps were signed into law by Democratic Governor Tony Evers. Two constitutional amendments aimed at limiting the governor's power to spend federal money are also on the ballot.
