Sanders-endorsed Russ Feingold has won the Democratic senate primary in the state of Wisconsin on Tuesday.
Feingold won a staggering 90 percent of the vote in the primary contest and will go on to face Senator Ron Johnson in November, a Republican who has held the seat since 2011.
The former Senator most recently served as United States Special Envoy for the African Great Lakes and the Congo-Kinshasa. Feingold previously represented Wisconsin in the United States Senate, but lost his seat in 2010 by just over 6 percent.
Feingold has a strong record on progressive issues. He voted against the Defense of Marriage Act in 1996, against the war in Iraq in 2002, he supports universal health care and has been a public supporter of marriage equality since 2006.
Bernie Sanders endorsed Feingold in May, and called on his supporters to contribute to his campaign.
“We are going to have to elect candidates up and down the ballot who recognize that it is too late for establishment politics and economics,” Sanders wrote at the time.
“Russ led the fight with me to make the Affordable Care Act much stronger in 2009. He voted against the USA PATRIOT Act and the war in Iraq. He authored and passed landmark campaign finance reform legislation and his campaign is powered by small-dollar contributions like ours.”
Recent opinion polls conducted in Wisconsin show Feingold with a healthy lead over Republican incumbent Ron Johnson. A Pollster average of the latest polls puts the Democrat in front with an eight point lead.
Clinton currently leads Trump by about nine points in Wisconsin.
