Donald Trump Jr. stopped in Wisconsin on Monday to make an urgent appeal to his father's supporters to vote in the state's Supreme Court election.

The involvement of the president's son is a reflection of the high stakes of the state court race, which has drawn national attention and lobbying from political A-listers on both sides, from Elon Musk to George Soros.

Early voting started on Tuesday in the pivotal April 1 race. Conservative Brad Schimel, a Waukesha County judge and Trump supporter, is up against Democrat-aligned Dane County judge Susan Crawford.

The race is a potential indicator of the nation's political temperature just a few months after Trump's historic re-election sent Democrats into a tailspin.

For the left, Wisconsin's race is an off-year opportunity to embarrass Trump and his top adviser, Elon Musk, even as judges around the country try to block much of the president's agenda.

If conservatives win, they will take back a narrow majority after losing control of the Supreme Court in 2023. The Supreme Court race that year was the most expensive judicial race in U.S. history at the time, but this year's contest is set to break that record.

The contest is partisan in everything but name. Democrats are framing the race around Musk, calling the election a referendum on a nascent "oligarchy." Meanwhile, progressive plutocrats like leftist billionaire George Soros and Illinois governor J. Pritzker (D) are pouring millions into the effort to elect Crawford, while Musk pours his money into backing Schimel.

The conservative candidate joined Trump Jr. at a Turning Point Action rally with Charlie Kirk, where Schimel warned that Crawford would help implement a "socialist" agenda.

"We have to stay vigilant," Schimel said. "If we want the voices of people with morality to be heard, if we want freedom-loving people, who don't want to be a socialist nation, to be heard, we have to get out and vote. And we've got to get our neighbors, our friends, our families, everybody to come with us. This is our mission. We've got to go and finish this job on April 1st."

Trump Jr. intervenes

With President Trump no longer on the ballot, his son warned Wisconsin conservatives not to get complacent.

"They're trying to negate the election. They're trying to negate the mandate. So we all have to just stay involved all the way through. It doesn't matter what it is. We can't just show up when Trump's on the ticket. We [have] to show up because we understand what [Democrats'] entire apparatus is trying to do to our country," he said.

Trump Jr. was also joined by former Republican governor Scott Walker, who noted the Supreme Court's power over congressional redistricting. Walker warned that liberals could use gerrymandering to endanger Republicans' razor-thin House majority.

Schimel seconded Trump Jr.'s urgent message.

"Do you think the job is done?” Schimel said. “We have to stay vigilant, and we have to stay on this."
