Wisconsin Supreme Court Justice Michael Gableman announced last week that he will not seek reelection to the state’s highest court. His seat is up in April 2018.

Former Michael Best attorney Michael Screnock, now a sitting Sauk County Circuit Court judge, announced that he will run for the Gableman spot. Gov. Scott Walker appointed Screnock to the Sauk County bench in 2015. If he prevails, the conservatives will maintain a 5-2 majority.

It is not yet clear whether Justice Gableman will stay on for the rest of his term or resign early to allow Walker an opportunity to appoint his third justice on the court. Any appointee by Walker would have to run in the first open election, which would be April 2018 for the open Gableman seat.

Also running are Madison attorney Tim Burns and Milwaukee Circuit Court Judge Rebecca Dallet, with Burns running as an unabashed progressive.
