Wisconsin's 8th congressional district is a congressional district of the United States House of Representatives in northeastern Wisconsin. It has been represented by Republican Tony Wied since November 12, 2024. It was previously vacant from April 24, 2024, following the effective date of the resignation of Mike Gallagher, a Republican. Gallagher won the open seat vacated by Reid Ribble who retired in 2016. It is also one of only two congressional districts to ever elect a Catholic priest, in the case of Wisconsin’s 8th, Robert John Cornell. The 8th District has leaned Republican throughout its history; seven Democrats have represented it since its creation, but none have served more than two terms. It became more of a swing seat in the 1990s. In 2004, Republican George W. Bush won 55 percent of the vote in the district, while in 2008, Democrat Barack Obama received 53.6 percent of the vote. The last Democrat to represent the district was Steve Kagen from 2007 to 2011. Since Kagen lost in the 2010 election, the seat has been held by Republicans, who have consistently won it by double-digit percent margins in each election to the seat since 2012 and won similarly in statewide elections. The only county in the current district to back the Democratic presidential candidate in the 2000, 2004, and 2016 elections was overwhelmingly Native American Menominee County, which has never voted Republican since its creation in 1960, and only Menominee and Door Counties voted Democratic in 2012 and 2020.
