Quick facts Representative, Distribution ...

The district has been represented by Democrat Diana DeGette since 1997. An urban and diverse district based in the heart of Metropolitan Denver, and with a Cook Partisan Voting Index rating of D+29, it is the most Democratic district in both Colorado and the Mountain West.^[3] Only two Republicans have been elected to the seat since the Great Depression: Dean M. Gillespie was the district's representative from 1944 to 1947; and Mike McKevitt from 1971 to 1973, winning thanks to an ideological split among Denver Democrats. No Republican has even notched 30% of the vote in the district after 1998.
