2024 Colorado House Election Interactive Map

All US House seats to be contested in 2024

Colorado gained an 8th district after the 2020 Census. In 2022, Democrats won the inaugural election for the seat by 0.7%, expanding their delegation majority to 5-3.

Districts 3 and 8 are the state's most competitive. While the District 8 margin was narrow, it was not the closest election in 2022. District 3, represented by Republican Lauren Boebert, was decided in her favor by just 0.2%. This was the closest House race nationwide.

To avoid another difficult general election, Boebert chose to run in CO-04, being vacated by the retiring Ken Buck. It is a safe Republican district which has drawn a number of candidates looking to succeed Buck.
