Wisconsin has eight seats in the House, apportioned according to the2000 United States census. Its 2007-2008 congressional delegation consisted of fiveDemocrats and threeRepublicans. That remained unchanged after the 2008 congressional elections in Wisconsin as all incumbent candidates won re-election, althoughCQ Politics had forecastedWisconsin's 8 district to be at some risk for the incumbent party.[1]
As of 2025, this is the last time the Democrats won a majority of congressional districts from Wisconsin. However, they would still go on to win the popular vote in several subsequent House elections.
In this relatively moderate district in southeastWisconsin, incumbent Republican CongressmanPaul Ryan has enjoyed popularity and faced no serious challenge from Democratic nominee, Marge Krupp, a chemist. DespiteBarack Obama'sstrong performance in Wisconsin that year in the presidential election, Ryan was re-elected overwhelmingly.
In this very liberal district based in theMadison metropolitan area, incumbent Democratic CongresswomanTammy Baldwin, the first openly lesbian member of theHouse, easily turned away a challenge from Republican candidate Peter Theron and won her sixth term with nearly seventy percent of the vote.
In this relatively liberal district based in westernWisconsin, incumbent Democratic CongressmanRon Kind easily won a seventh term over Republican challenger Paul Stark.
Incumbent Democratic CongresswomanGwen Moore, running for her third term, faced easy re-election prospects in this highly liberal district based inMilwaukee; no Republican candidate filed to run against her. Moore defeated independent candidate Michael LaForest in a landslide.
In the wealthiest and most conservative district in Wisconsin, based in the northern suburbs ofMilwaukee, long-serving incumbent Republican CongressmanJim Sensenbrenner easily defeated his only challenger, independent candidateRobert R. Raymond, to win a sixteenth term in Congress.
This traditionally conservative district based in theOshkosh-Neenah,Metropolitan Statistical Area was narrowly won by Democratic nomineeBarack Obama in the2008 election, but long-serving Republican incumbent CongressmanTom Petri held a tight grip on his seat. Petri sought and won a sixteenth term against Democratic candidate Roger Kittelson, winning handily.
Long-serving incumbent Democratic CongressmanDave Obey held an iron grip on this district based in northwesternWisconsin for forty years. Seeking a twenty-first term in Congress, Obey was overwhelmingly re-elected again over Republican challenger Dan Mielke despite the centrist nature of the district.
Incumbent CongressmanSteve Kagen faced off against formerWisconsin State Assembly SpeakerJohn Gard for a second time in this Republican-leaning district that is based in northeasternWisconsin and that includes the cities ofGreen Bay andAppleton. Seeking a second term, Kagen defeated Gard by a larger margin than he did in 2006, allowing him to keep this swing district under Democratic control.
