Colorado's 2nd congressional district

Colorado's 2nd congressional district is a congressional district in the U.S. state of Colorado. The district is located in the north-central part of the state and encompasses the northwestern suburbs of Denver including Boulder and Fort Collins. The district also includes the mountain towns of Vail, Granby, Steamboat Springs, and Idaho Springs. Redistricting in 2011 moved Larimer County, including the cities of Fort Collins and Loveland, to the 2nd from the 4th district. Meanwhile, redistricting in 2021 moved Loveland back to the 4th district and Broomfield and western Jefferson County to the 7th district.

The district is currently represented by Democrat Joe Neguse. He was elected in 2018 to replace Jared Polis, who retired after being elected governor of Colorado.

Characteristics
This district is anchored in Boulder and Larimer counties which have the bulk of population in the district: both counties are mainly anchored by the large college towns of Boulder and Fort Collins, providing Democratic strength in the district.

The other parts of the district are diverse, ranging from far western Denver suburbs to agricultural areas and mountain towns. Eagle and Summit counties, home to the ski resort towns of Vail and Breckenridge and other tourism dependent towns such as Avon, Frisco and Silverthorne, are Democratic strongholds: however Gilpin and Clear Creek counties, while also being tourism dependent and Democratic leaning, do not vote as strongly for the Democrats. Grand County leans Republican, though the ski resort areas of the county in Winter Park are heavily Democratic.

The suburban areas of Denver represented in the 2nd district are more competitive; while Broomfield itself leans Democratic, the Jefferson County foothills are historically a Republican stronghold, though urban sprawl is eroding Republican dominance in the area. Similarly, Larimer County outside of Fort Collins is heavily Republican, however the county leans Democratic due to the influence and population of Fort Collins.
