The 2018 United States House of Representatives elections in Wisconsin were held on November 6, 2018, to elect the eight U.S. representatives from the state of Wisconsin, one from each of the state's eight congressional districts. The elections coincided with other elections to the House of Representatives, elections to the United States Senate, and various state and local elections. The Wisconsin Partisan Primary was held on August 14, 2018, with the governor, U.S. Senator, U.S. Representative, odd-numbered Wisconsin State Senate seats, and all Wisconsin Assembly seats on the ballot.[1]
Wisconsin was notable for being the only state in which the party that won the popular vote still held a minority of congressional seats in 2018. The Milwaukee Journal Sentinel attributed this to the impact of gerrymandering imposed by the Republican-controlled Wisconsin Legislature in 2011.[2]

See also: Wisconsin's 1st congressional district. The 1st congressional district is located in southeastern Wisconsin, covering Kenosha County, Racine County and most of Walworth County, as well as portions of Rock County, Waukesha County and Milwaukee County. Incumbent Republican Paul Ryan, Speaker of the House and Republican nominee for Vice President in the 2012 who had represented the district since 1999, did not run for re-election. He was re-elected with 65% of the vote in 2016. The district had a PVI of R+5.
Ryan could potentially have seen a close race; in hypothetical polling, his main Democratic challenger, Randy Bryce, was behind Ryan by only seven points. Ryan was also facing challenges in the Republican primary from Paul Nehlen, who also challenged Ryan in 2016, and from Nick Polce. Ryan announced on April 11, 2018, that he is not seeking re-election. On April 22, Bryan Steil, member of the University of Wisconsin Board of Regents and former personal driver to Ryan, announced his bid for the seat, with news outlets reporting Steil as the Republican Party nominee front-runner.[4]
Two Democrats announced; ironworker Randy Bryce and Janesville school board member Cathy Myers.
