President Donald Trump‘s former senior campaign adviser Jason Miller said Wednesday that Republicans need to get “aggressive” following the Democrat-backed victory in Wisconsin‘s Supreme Court special election.

Susan Crawford, a liberal, won a seat on the Wisconsin Supreme Court on Tuesday, easily defeating her Musk-backed conservative challenger, Brad Schimel, in a race Musk said “might decide the future of America and Western civilization.”

Elon Musk poured millions of dollars into a Wisconsin Supreme Court race and even donned a local cheese-shaped hat at a political rally, only to have his candidate soundly defeated in a race viewed as an early referendum on Donald Trump's presidency.

The liberal prevailed in a technically nonpartisan Wisconsin State Supreme Court race that took on national importance. Voter turnout is an indication that Americans remain deeply engaged in the electoral process.

Democrat-backed Susan Crawford won the closely-watched Wisconsin Supreme Court race, the most expensive judicial election in U.S. history.

A Marquette University Law School poll taken in late February also found that a majority of registered voters in Wisconsin support photo ID for voting, and separately, a majority of registered voters in Wisconsin said they would support the ballot initiative.

The Democratic-backed candidate for Wisconsin Supreme Court has won, defeating President Donald Trump’s endorsed challenger.

Record turnout and a backlash against Trump and Elon Musk, who had largely hijacked the campaign, played a role.
