Colorado's 8th congressional district is a congressional district in the U.S. state of Colorado. The district was apportioned after the 2020 United States census. The first congressional seat to be added to Colorado's congressional delegation since 2001, the 8th district was drawn before the 2022 elections. The district was drawn by the Colorado Independent Redistricting Commission and approved in an 11âÂÂ1 vote on September 28, 2021, before being approved unanimously by the Colorado Supreme Court on November 1, 2021. It has been represented by Republican Gabe Evans since 2025.
The district is one of seven with a Cook Partisan Voting Index of EVEN, meaning that the district votes almost identically to the national electorate. It was also identified as a presidential bellwether district by Sabato's Crystal Ball, having voted for the Electoral College winner in the past four presidential elections as of 2020.
Colorado's 8th congressional district stretches along Interstate 25, encompassing sections of Adams County, Larimer County, and Weld County. The largest population centers are Brighton, Commerce City, Greeley, Johnstown, Northglenn, and Thornton. The district has the largest number of Hispanic residents of any congressional district in Colorado, making up 38.5% of the adult population. The 8th congressional district is viewed as competitive, with the Democratic Party holding a 3% lead in active registered voters and an average margin of victory of 1.3% between eight statewide elections held between 2016 and 2020. Joe Biden won the area that is now the 8th district by 4.7% in the 2020 United States presidential election. Republicans are strongest in Greeley and Weld County, while the northern Denver suburbs in Adams County lean Democratic.
