On January 4, 2019, incumbent Republican Senator Pat Roberts announced he would not run for a fifth term. Candidates had until June 1, 2020 to file to run for the open seat or to drop out if they already filed. The U.S. Senate primaries were held on August 4, 2020.
Republican U.S. Representative Roger Marshall was considered a narrow favorite based on polling, but he won by around 11 points, a larger margin than most experts predicted. However, this was the first Senate election since 1978 where a Democrat won Shawnee County, the first Senate election since 1974 where a Democrat won Riley County, and the first Senate election ever in Kansas's history where a Democrat won Johnson County; all three counties were also flipped by Democrat Joe Biden in the concurrent presidential election.
