Wisconsin's 3rd congressional district

Wisconsin's 3rd congressional district is a congressional district in Wisconsin. It has been represented by Democrat Ron Kind since 1997. It is located in western Wisconsin, along the Minnesota-Wisconsin border. The district has a Cook Partisan Voting Index of R+4, meaning it is roughly four points more conservative than the country. It is one of just seven districts to support Donald Trump in 2020 but also elect a representative from the Democratic Party.
Political characteristics.
This district used to favor the Democrats, but has recently begun favoring Republicans slightly. This can be seen by Representative Kind's decreasing margins in recent years: he won 56.5% in 2014, 99.9% in 2016 (he had no opponent), and 59.7% in 2018 - all high percentages - but just 51.3% in 2020, a very narrow victory. The district has also gone from supporting Democrat Barack Obama in 2012, 55-44%, to supporting Republican Donald Trump 49-44% in 2016 and 52-47% in 2020, and the Cook PVI went from even (meaning it was as competitive as the country) to R+4 (meaning it was conservative-leaning). With popular Representative Kind having announced his retirement, some think the district will elect a Republican representative in 2022 for the first time in the 21st century.
