Wisconsin Is Set to Vote on Tuesday After Court Overrules Governor’s Postponement

Wisconsin’s Supreme Court ruled on Monday that the governor could not postpone Tuesday’s elections because of concerns about the coronavirus, a decision that throws into chaos a presidential primary and nearly 4,000 local contests.

The court ruled 4-2, along ideological lines, that Gov. Tony Evers, a Democrat, could not use emergency powers to unilaterally change the date of the election, which he sought to do to circumvent Republican opposition to the move.

Mr. Evers had previously said he lacked the legal authority to delay the election and had called upon the Republican-controlled Legislature to reschedule it. But on Monday Mr. Evers argued that a postponement was necessary to protect voters and slow the spread of the virus. Within minutes of the order, Republican lawmakers called his move unconstitutional, instructing clerks to move forward with voting.

The Legislature’s leaders then challenged the order in the Wisconsin Supreme Court, which is controlled by a conservative majority.
