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.
An urban and diverse district based in the heart of Metropolitan Denver, this district is the most Democratic district in the Mountain West. Only two Republicans have been elected to the district's Congressional seat since the Great Depression. Dean M. Gillespie was the district's representative from 1944 to 1947, and Mike McKevitt served one term from 1971 to 1973, winning thanks to an ideological split among Denver Democrats.
