The year's first major political test in Wisconsin becomes a referendum on Elon Musk

The election to fill a Wisconsin Supreme Court seat has become a referendum not only on the new administration, but on Elon Musk, the billionaire who has become one of President Donald Trump 's top financial backers and the architect of his efforts to slash the federal workforce.

The April 1 election is the first major test in American politics since Trump secured a second term in November. It will serve as a crucial barometer of enthusiasm in both parties heading into next year's midterm elections and is happening in a critical battleground state that Trump won by less than a percentage point.

It's also a test for Musk himself. The Tesla CEO's nascent political operation, which spent more than $200 million to help Trump win in November, is canvassing and advertising in Wisconsin on behalf of the conservative candidate. A win would cement his status as a conservative kingmaker, while a loss could give license to Republicans distancing themselves from his efforts to stymie government functions and eliminate tens of thousands of jobs.

“This is the first major election held since Donald Trump took office,” said Anthony Chergosky, a political science professor at the University of Wisconsin-La Crosse. “And I think notably Democrats are concentrating more on Elon Musk than Donald Trump.”

Musk, who is the race's biggest donor by far, has also inserted himself into the race, holding a get-out-the-vote event on his X platform Saturday.

“It might not seem important, but it’s actually really important. And it could determine the fate of the country,” he said. “This election is going to affect everyone in the United States.”

April 1’s election will determine majority control of a court facing critical issues: abortion rights, collective bargaining and voter access. They include decisions that could have major implications for the 2026 midterms and 2028 presidential election, particularly if they end up hearing challenges to the state’s congressional maps, which could theoretically swing the balance of power in Washington if they are considerably redrawn.

In 2020, the court rejected Trump’s attempts to overturn his election loss in the battleground state in a 4-3 ruling. Trump had sought to have 221,000 ballots disqualified in the state’s two most Democratic counties.

Trump inflatables and America PAC petitions

The Supreme Court race is officially nonpartisan, but the campaign has been anything but. Brad Schimel, the Republican-backed candidate, has openly courted Trump's endorsement, which he received on Friday night, as he campaigns against Dane County Judge Susan Crawford, the Democrat-backed candidate.

The Waukesha County judge and former Republican attorney general attended the president’s inauguration in January, has said that he would be part of a “support system” for Trump. Earlier this month, he attended a “Mega MAGA rally” where he posed for a picture in front of a giant inflatable version of the president, which had a “Vote Brad Schimel Supreme Court” poster plastered on its chest.

He spoke on Musk's get-out-the-vote call on Saturday. And he joined the president’s eldest son on stage at a get-out-the-vote rally, where Donald Trump Jr. said a Schimel win would protect his father’s agenda and keep up GOP momentum.

“We can’t just show up when Trump’s on the ticket,” he said at a brewery in the Milwaukee suburbs. “You have to engage because it’s not just about now, it’s about that future. This presidency could be put to a halt with this vote.”

Schimel has also resurfaced long-debunked conspiracies about voter fraud that Trump has embraced, urging his supporters to vote early to “make this too big to rig so we don’t have to worry that at 11:30 in Milwaukee, they’re going to find bags of ballots that they forgot to put into the machines.”

Still, he pledged to judge any case that comes before him on its merits — including potential cases involving Trump and Musk.

Republicans have cast the race as a chance for Trump’s loyal supporters to rally around their leader and push back against liberal judges they accuse of working to stymie his agenda.

Mailers from Musk’s America PAC feature photographs of the president. “President Donald Trump needs your vote,” they read. Others warn that “Liberal Susan Crawford will stop President Trump’s agenda.”

America PAC is also offering Wisconsin voters $100 to sign a petition in opposition to “activist judges” — and another $100 for each signer they refer.

Republicans have argued that if even 60% of the voters who cast ballots for Trump in November turn out, Schimel can win, helping to drive momentum for the party heading into next year's midterms.

“In theory, the opposition party should be energized, but we’re feeling very good about the energy on our side of the aisle,” said Andrew Iverson, Wisconsin GOP executive director.

Andrew Romeo, senior adviser to the Musk-backed group Building America’s Future, which has spent millions on the race, issued a recent memo advising Schimel’s campaign to remind voters that he is “a strong conservative and Trump ally.”

Two groups funded by Musk have so far spent more than $14 million on the race, according to a tally by the liberal Brennan Center for Justice — with plans to spend around $20 million total.

Musk donated another $2 million to the Wisconsin Republican Party on Thursday, the same day the party gave $1.2 million to Schimel’s campaign.

Under Wisconsin law, contributions to candidates are capped, but candidates can accept unlimited cash from state parties, which in turn can accept unlimited cash from donors.

His spending has helped make the race the most expensive judicial election in the nation’s history, with more than $73 million spent so far, according to the Brennan Center, breaking the record set by another Wisconsin Supreme Court race two years ago.

Crawford has also received her own support from billionaires, including philanthropist George Soros and Illinois Gov. JB Pritzker.

Democrats want the race to be ‘The People vs. Musk’

Democrats are hoping to channel their voters’ outrage at the Trump administration by casting the race as an opportunity to stand up to Musk. After nearly a decade of running against the president, they see Musk as a potentially more divisive figure who can motivate their base voters to turn out.

“This race is the first real test point in the country on Elon Musk and his influence on our politics, and voters want an opportunity to push back on that and the influence he is trying to make on Wisconsin and the rest of country,” said Crawford campaign spokesperson Derrick Honeyman.

State Democrats have hosted a series of anti-Musk town halls, including one featuring former vice presidential candidate Tim Walz, and featured Musk heavily in ads.

Crawford has also seized on Musk, going as far as to refer to her opponent as “Elon Schimel” during a recent debate.

“Don’t let Elon buy the Supreme Court,” read billboards paid for the state Democratic party that depict Musk as Schimel’s puppeteer.

“There’s so many people who are desperate for a way to fight back against what Trump and Musk are doing nationally,” said Ben Wikler, the Wisconsin Democratic Party chair, and see the race as an “opportunity to punch back.”

Wikler said the party had seen an “explosive surge” in grassroots and small-donor fundraising from across the country tied to Musk’s involvement. Both in Wisconsin and nationally, Democrats are packing town halls and angrily protesting the Trump administration’s firings of thousands of workers and shutdown of agencies. They have also show disillusionment with their party’s own leaders.

“Most voters still don't know who Crawford and and Schimel are, but they have extremely strong feelings about Musk and Trump," he said.

What's at stake for Musk

Musk said Saturday that he became involved in the race because it “will decide how the Congressional districts are drawn in Wisconsin,” echoing Schimel’s claims that Crawford would push through new congressional maps that could favor Democrats.

Schimel’s campaign has relentlessly attacked Crawford for participating in a call with Democratic donors that was advertised in an email as a “chance to put two more House seats in play for 2026,” a reference to the state's redistricting fights that have played out for years.

Crawford has said that she didn’t know that that was how the call had been billed when she joined and that nothing of that nature had been discussed while she was on the line.

“In my opinion, that’s the most important thing, which is a big deal given that the Congressional majority is so razor-thin,” Musk said. “It could cause the House to switch to Democrat if that redrawing takes place, and then we wouldn’t be able to get through the changes that the American people want.”

Musk has also been giving money to Republican members of Congress who have echoed his calls to impeach federal judges whose decisions he doesn’t like.

He has other interests at play.

Democrats and Crawford have noted that, just days before Musk’s groups started spending on the race, Musk’s electric car company Tesla sued Wisconsin over a rule banning car manufacturers from operating dealerships — forcing buyers to purchase Teslas out of state.

The case could ultimately go before the Wisconsin Supreme Court.
