The April 1 Wisconsin Supreme Court election was the most expensive U.S. court race in history, drawing more than $100 million in campaign spending.
That eye-popping figure has drawn plenty of headlines — as did the millions spent by billionaire Elon Musk to support Republican-backed Waukesha County Judge Brad Schimel, who lost handily to Dane County Judge Susan Crawford, backed by Democrats.
But the race also set another record in Wisconsin for a spring election not featuring a presidential primary contest: in voter turnout.
More than 2.3 million people cast ballots in the election, according to Associated Press tracking. That amounts to nearly 51% of the voting age population, shattering the previous record for such elections of 39% in 2023.
The high turnout is part of a trend in Wisconsin politics since President Donald Trump’s first election in 2016, Marquette University’s John Johnson wrote in an analysis last week.
“Wisconsin’s electorate is just plain extremely engaged,” he wrote. “Scour American history and you’ll struggle to find an example of (a) state as hyper-engaged with, and narrowly divided by, electoral politics as Wisconsin in the present moment.”
Last week’s election offered good news for Democrats, aside from the top-line figures in Crawford’s 55%-45% win. (The Supreme Court is officially nonpartisan, but Democrats backed Crawford, while Republicans backed Schimel.)
When comparing the high-turnout 2024 presidential election to the latest Supreme Court race, voting shifted toward the Democratic-backed candidate in all 72 counties.
The biggest difference in the latest election, according to Johnson: “A majority of the million voters who stayed home are probably Republicans, or at least Trump supporters.”
More broadly, it’s clear that the high stakes of the Supreme Court race drove most to cast ballots in an election that also included an officially nonpartisan contest for state superintendent of public instruction and a successful ballot measure to enshrine voter ID requirements in the Wisconsin Constitution.
Nearly 200,000 people who cast ballots did not choose a superintendent candidate. Democratic-backed incumbent Jill Underly prevailed over Republican-backed Brittany Kinser by a 53%-47% margin — closer than the Supreme Court race.
Additionally, about 76,000 voters did not weigh in on the voter ID amendment.
