MADISON, Wis. (AP) — Candidates in a race that will determine ideological control of the Wisconsin Supreme Court will square off in their only scheduled debate before the April 1 election.

The contest will serve as a litmus test early in President Donald Trump’s term in a key presidential swing state. Control of the court is on the line as it faces cases over abortion and reproductive rights, the strength of public sector unions, voting rules and congressional district boundaries.

The race pits Waukesha County Circuit Judge Brad Schimel, a former Republican attorney general, against Dane County Circuit Judge Susan Crawford, who is running in her first statewide race. The debate starts at 7 p.m. Wednesday.

It can be watched on WISN’s website, or on ABC affiliates, such as Eau Claire’s WQOW.
