Colorado's 1st congressional district
Colorado's 1st congressional district is a congressional district in the U.S. state of Colorado based primarily in the City and County of Denver in the central part of the state. The district includes all of the City and County of Denver and the nearby suburbs of Glendale, Englewood, Sheridan, and Cherry Hills Village.
The district has been represented by Democrat Diana DeGette since 1997.
Based in the heart of Metropolitan Denver, this district is by far the most liberal district in the non-coastal parts of the American West and the most liberal district in the western US outside of Los Angeles, San Francisco, Portland, Hawaii, and Seattle. While there is some GOP strength in the suburban areas, the GOP strength here is no match for the overwhelming Democratic tilt of the City of Denver.
History
1990s
Following the 1990 U.S. Census and associated realignment of Colorado congressional districts, the 1st Congressional district consisted of all of the City and County of Denver and parts of Adams, Arapahoe, and Jefferson counties.
