MADISON, Wis. (AP) - In a significant shakeup for Wisconsin politics, seven incumbent legislators have lost their seats following the primaries held on Tuesday. This development comes after the liberal-controlled state Supreme Court adopted new legislative district boundaries drawn up by Democratic Gov. Tony Evers earlier this year. These new maps led to several legislative incumbents facing off against each other, resulting in some unexpected outcomes.

Among those who were ousted is Republican Rep. Janel Brandtjen, who represented Milwaukee's northwestern suburbs since 2014. Brandtjen gained notoriety for refusing to accept that President Joe Biden won Wisconsin in 2020 and calling for the firing of Wisconsin Elections Commission Administrator Meagan Wolfe. She also accused Assembly Speaker Robin Vos of not doing enough to investigate the election results and supported two failed recall efforts against him. Despite receiving President Donald Trump's endorsement, Vos barred Brandtjen from GOP caucuses.

Brandtjen faced Republican Sen. Dan Knodl in the primaries after new maps left Knodl in the same Senate district as Republican Sen. Duey Stroebel. Knodl emerged victorious with 65% of the votes, while Brandtjen did not respond to a voicemail on Wednesday. Knodl is considered more moderate than Brandtjen but also signed a letter alongside other legislators asking then-Vice President Mike Pence to delay certifying Biden's win. Knodl will now face Democrat William Walter in November. Walter serves as executive director of Our Wisconsin Revolution, a group that mobilizes against "the reckless abuse of power by rich elites."

In another notable primary defeat for an election denier, Republican Sen. Dan Feyen defeated former state representative and gubernatorial candidate Timothy Ramthun for a seat representing the Fox Cities. Ramthun gained attention by pushing to decertify Biden's win and garnered support from Trump. However, Feyen secured 64% of the votes and will face Democrat Michael Rapp in November.

The new maps also led to Rep. Michael Schraa facing off against freshman Rep. Nate Gustafson in a district representing parts of the Fox Cities. Schraa has been a leading voice on prison reform but was defeated by Gustafson, who received about 55% of the votes. Gustafon will now face Democrat Kyle Kehoe, a Fox Cities real estate agent, in November.

In central Wisconsin, Rep. John Spiros emerged victorious against Rep. Donna Rozar in a GOP primary for a seat representing the Marshfield area after redistricting shifted Rozar into Spiros' district. Spiros will now face former Marathon County Supervisor John Small in November.

The outcome of a Republican primary in northern Wisconsin remains uncertain due to ballot problems. Voters in the Douglas County town of Summit were mistakenly given ballots listing candidates in a Democratic primary in another Assembly district, preventing them from voting in their own district's Republican primary between Rep. Chanz Green and former prison guard Scott Harbridge. County Clerk Kaci Jo Lundgren took responsibility for the mistake, acknowledging that she didn't realize Summit had been moved into a different district due to redistricting.

As of Wednesday morning, unofficial results showed Green leading Harbridge by 968 votes. However, Harbridge refused to concede and expressed interest in exploring legal options regarding the ballot issue. Green's voicemail was full on Wednesday morning.

The primaries have set the stage for November's elections, where Democrats aim to make substantial gains in the Legislature for the first time since 2010. While they concede that seizing control of the Senate is unlikely this cycle, retirements and redistricting have left almost 60 of the Assembly's 99 seats open, providing an opportunity for Democrats to potentially regain the majority.

In addition to determining the winners of seven open Assembly seats and two open Senate seats outright, the primaries have set up competitive races for November. With almost 60 open seats in the Assembly and one open seat in the Senate, both parties are gearing up for a significant electoral battle.

The primaries have marked the beginning of an intense electoral season in Wisconsin, with the new legislative district boundaries fueling Democrats' hopes of making substantial gains in the Legislature. As November approaches, both parties are preparing for what promises to be a closely-contested battle for control.
