Minnesota's 1st congressional district

Minnesota's 1st congressional district spans southern Minnesota from the border with South Dakota to the border with Wisconsin. It is a primarily rural district built on a strong history of agriculture, though this is changing rapidly due to population growth in the Rochester combined statistical area. The district also includes several of Minnesota's major mid-sized cities, such as Rochester, Mankato, Winona, Austin, Owatonna, Albert Lea, Red Wing, New Ulm, Worthington, and Lake City. It is currently represented by Republican Brad Finstad.

From the state's early years until after the 2000 census, the district encompassed only southeastern Minnesota. Throughout the 20th century, it was generally regarded as solidly Republican, but it became more of a swing district in the late 20th and early 21st centuries. In 2004, John Kerry received 47% of the vote in the district. In 2006, Republican Representative Gil Gutknecht lost to Democrat Tim Walz. In March 2017, Walz announced that he would not run for reelection to Congress and would instead run for governor of Minnesota. On paper, the district leans Republican, with a CPVI of R+6, but some recent elections have been among the closest in the nation, with victories by less than a single percentage point in both 2016 and 2018. In the 2022 general election, Republican Brad Finstad defeated the Democratic nominee by 11.5 points. His margin of victory was the largest of any candidate's in the district since 2012 and the best showing for a Republican since 2004.
