The statewide spring primary for Wisconsin was held on Feb. 16, 2021. If two or fewer candidates filed for each seat on the ballot, the primary was canceled and the candidates automatically advanced to the general election on April 6.
The primary for the Wisconsin superintendent of public instruction was the only statewide nonpartisan race on the ballot. Incumbent Carolyn Stanford Taylor did not file to run for election. Taylor was first appointed to the position in January 2019 by Gov. Tony Evers (D), who resigned the seat after being elected governor in 2018. Seven candidates filed to run in the race. According to unofficial results, the highest number of votes went to Jill Underly (27.3%) and Deborah Kerr (26.5%). Both candidates advanced to the general election.
Two partisan state legislative special elections were on the otherwise nonpartisan ballot.
Wisconsin state Senate District 13 became vacant on Jan. 1 after Scott Fitzgerald (R) was elected to the U.S. House. One Democrat, three Republicans, and two independent candidates filed for the seat. John Jagler defeated Todd Menzel and Don Pridemore in the Republican primary, receiving 57.1% of the unofficial vote. He faces Melissa Winker (D), Ben Schmitz (American Solidarity Party), and Spencer Zimmerman (Trump Conservative Party) in the general election.
State Assembly District 89 became vacant on Dec. 2, 2020, after John Nygren (R) resigned his seat to work in the private sector. One Democrat and five Republicans filed for the seat. Elijah Behnke won the Republican primary with 44.5% of the unofficial vote. He faces Karl Jaeger (D) in the general election.
The general election ballot will feature more offices, including three state appellate court seats and local nonpartisan seats.
