All 7 of Colorado’s US House of Representatives seats are up for election in 2020.  In addition, elections will be held for President, US Senate, half of the 35 state Senate seats, and all 65 of the state House of Representatives seats.  All of the federal races, all of the statewide races, and every state legislature race (house or senate) where the margin of victory was 10% or less in the last 4 years (per iffr.wiki) are listed below. The party of the incumbent is indicated by the office name being in blue (incumbent is a Democrat) or red (incumbent is a Republican). The Democratic (blue) and Republican (red) candidates are listed, with the incumbent indicated (I).

Note the Colorado Senate is currently Democratic controlled with an 1916 majority and the Colorado House is Democratic controlled with a 4124 majority.

Perhaps your group might be interested in getting involved in one or more of these elections.  We’re listing groups here who’ve let us know they are interested in specific elections.  If you’d like your group’s interest in a specific election to be listed here or in an election not listed here (we’ll add it), please let us know. Your group does not have to be an Indivisible group to be listed. “Interest” does not necessarily mean your group has endorsed a particular candidate and does not mean your group is coordinating with any campaign. Individual groups are free to endorse candidates and coordinate with campaigns as desired.
