Anyone needing proof of the power and significance of the Wisconsin Supreme Court can look no further than the lines of mask-wearing voters that stretched for hours in Milwaukee during an election held despite a stay-at-home order because of the coronavirus pandemic.

An election-eve decision by the court overturning the governor’s order to postpone the vote made the state an outlier in pushing ahead with voting, ignoring pleadings from health experts and local officials about the danger of spreading the virus.

The fact that Wisconsin went forward when other states delayed their elections, and that many voters were willing to endure long waits to cast ballots, reflects the hotly disputed role the court has taken in a state with outsize importance in national politics.

Republicans and Democrats both see Wisconsin as crucial to winning national elections and gaining control of Congress. Historically, elections in the state are decided by close margins and power has flipped between the parties.

Since conservatives have held a majority on the state Supreme Court, the Republican-dominated Legislature has been able to enact laws that enhanced the GOP’s position, including voter ID laws and limits on labor unions, despite legal challenges from Democrats. The court would play a pivotal role in reviewing the drawing of new district lines for legislative and congressional offices following the 2020 census, which has a major impact on the balance of political power.

On the ballot Tuesday for a 10-year term was one of the justices in the court’s 5-2 conservative majority, Dan Kelly.

Democrats charged that holding the election when many voters might stay home would unduly benefit Republicans, who generally fare better in low-turnout ballots. Wisconsin’s Supreme Court elections are nonpartisan in name only.

No turnout information was available from Tuesday’s vote. The results can’t be posted until April 13, allowing time for counting absentee ballots.
