A liberal challenger on Monday ousted a conservative Wisconsin Supreme Court justice endorsed by President Donald Trump, overcoming a successful push by Republicans to forge ahead with last week’s election even as numerous other states postponed theirs due to the coronavirus pandemic.

Joe Biden also emerged victorious, as expected, in the state’s Democratic presidential primary. Biden’s easy victory became academic when Vermont Sen. Bernie Sanders dropped out, one day after Wisconsin held in-person voting.

But the absentee-ballot-fueled victory by liberal Supreme Court candidate Jill Karofsky was a huge win for Democrats. It reduced conservative control of the court to 4-3, giving liberals a chance to take control in 2023.

Karofsky will now be on the court when the Republican-controlled Legislature tackles redistricting next year, a fight many expect to be decided by the state Supreme Court.

Her win will also certainly be seen as a bellwether in battleground Wisconsin ahead of the November presidential election. Trump barely carried the state four years ago, and both parties see it as critical this year.
