Wisconsin voters cast ballots on Tuesday in partisan primaries for governor and several U.S. House seats, choosing nominees ahead of the November general election. Polling places across the state opened under rules set by the Wisconsin Elections Commission.

The primaries determine which candidates will advance in the governor's race and in contested congressional districts. Local outlets tracked hopefuls campaigning across western and central Wisconsin in the closing days before the vote, including coverage of Republican U.S. House candidate Steve Friess in Rock Springs.

Immigration enforcement and the economy have shaped the contests, echoing themes visible in other 2026 primaries. President Donald Trump's immigration crackdown has featured prominently in Democratic and Republican messaging, with candidates staking out positions on federal enforcement and its impact on Wisconsin communities.

The Wisconsin Elections Commission urged voters to check registration status and polling locations. Results will be reported as counties complete tabulation.

Turnout in an August primary is typically lower than in November, and both parties invested in get-out-the-vote operations in swing districts. Wisconsin remains a critical battleground, and the outcome will help define the state's political map heading into the fall.

Democratic Party of Wisconsin and Republican Party of Wisconsin officials said they expected competitive general-election matchups.
