Two Democrats entered the race on Monday to succeed Republican Sean Duffy in Congress.
Tricia Zunker is the president of the Wausau School Board and a justice on the Ho-Chunk Nation Supreme Court.
She’s trying to become the first Native American elected to Congress from Wisconsin.
Businessman and Vietnam War veteran Lawrence Dale also will run as a Democrat.
Dale unsuccessfully challenged Duffy in 2014 as a Green Party candidate, then failed to win a Democratic primary for State Assembly in 2016.
