On April 6, Monday, Wisconsin Governor Tony Evers delayed the April 7 election until June 9. The proclamation says the June 9 would be changed to another date if the legislature passes a bill setting a different date.
The most important part of the April 7 are non-partisan judicial races, including a State Supreme Court race. The April 7 date is also for the state’s presidential primaries for the Democratic and Republican Parties. Here is the proclamation. Thanks to Rick Hasen for the link.
