The latest in Colorado

Sept. 16, 2021

Colorado’s new independent redistricting committee released its second map proposal on Sept. 15, after listening to public feedback. The partisan makeup of the new map is quite similar to the previous proposal — three likely Democratic seats, three likely Republican seats and two competitive seats. However, breaking with the previous proposal, this map keeps incumbents generally in their current districts, with one open seat, as Colorado is gaining an extra House seat this cycle. (The previous map had drawn some criticism for unifying southern Colorado and northern Colorado into one district each and, as a result, putting some incumbents — such as Reps. Joe Neguse and Lauren Boebert — into the same district.)

Like the previous proposal, this map also addresses some of the concerns of Hispanic interest groups by creating a district — the 8th — that is about a third Hispanic by voting-age population. That may give Hispanic voters in the 8th District a greater likelihood of electing their candidate of choice.

The map will likely still displease Democrats, who currently control four of Colorado’s seven congressional seats, as it puts Republicans and Democrats on about equal footing in terms of winnable seats even though the state has become bluer in recent years and Democrats currently control all parts of state government. If the state does continue to trend blue, the two proposed competitive seats could inch closer to the Democratic column over the coming decade, but that’s no guarantee.

This new iteration of Colorado’s congressional map may closely resemble what is ultimately submitted to the state Supreme Court. The commission has a deadline of drawing up a final map by Oct. 1.
