Democrats scored a critical win Tuesday in their first major test at the ballot box since President Trump took office in January.

The elections came amid growing anger over the Trump’s administration’s immigration and economic policies, its handling of free speech, and the federal cuts made under Elon Musk’s Department of Government Efficiency (DOGE).

The night served in part as a referendum on Musk, who has played an outsized role in the administration and poured millions of dollars into the Wisconsin race.

It's only been five months since voters in Wisconsin faced a bitterly fought election, but residents of the US state are already heading back to the polls.

This time, Elon Musk looms large in the race to fill a vacancy on the Wisconsin Supreme Court, even if the billionaire's name doesn't appear on the ballot.

It's the most expensive judicial contest in US history, with more than $90m (£70m) spent so far, including $20m from Musk and groups affiliated with him.

A Wisconsin appellate court denied the state Democratic attorney general’s request to stop billionaire Elon Musk from handing over $1 million checks to two voters at a rally planned for Sunday, just two days before a closely contested Supreme Court election.

The world’s richest man gave away $1 million to a voter who signed his petition—for the second time.

A political action committee funded by Elon Musk has announced the first $1 million winner in its petition against "activist judges" in Wisconsin.

Elon Musk’s America PAC awarded its first $1 million prize to a registered Wisconsin voter after he signed a petition against “activist judges.”

Angela Lang is about to send her canvassing teams door knocking. But first, a moment to outline the stakes:

“Fair maps, abortion, voting rights,” is Lang’s list. “It’s not a seat we can afford to lose because if Republicans and conservatives gain control of the court, that’s Elon Musk and that’s a through line to the Trump agenda.”

President Donald Trump and billionaire adviser Elon Musk are going all-in on flipping control of Wisconsin’s top court, with Trump endorsing the conservative in the race and Musk’s PAC hunting for votes by offering state residents cash for their contact details.

The burst of support comes as Trump faces his first test with swing-state voters in the April 1 election since winning a second term in November. The court is expected to decide the future of abortion in the state and could redraw a congressional map that has given Republicans six of the state’s eight seats.

Democrats in Wisconsin are trying to use a state judicial race as a referendum on Elon Musk.

In the final 10 days of the high-profile state Supreme Court campaign, the Democratic Party of Wisconsin is blanketing the TV airwaves with two new ads that put Musk front-and-center. The ads, shared first with POLITICO and part of a seven-figure investment in Musk-related ads and events, link the billionaire and his Department of Government Efficiency to Brad Schmiel, the state’s former GOP attorney general who’s now running for the seat.
