NEWS BRIEF

The Denver Gazette reports that Colorado voters will decide in November whether Amendment 86 should establish constitutional requirements for changes to congressional district maps outside the regular redistricting cycle. The measure would require approval by the Independent Congressional Redistricting Commission and the Colorado Supreme Court.

Colorado’s current congressional maps were approved in 2021, and the next regular redistricting is scheduled for 2031. Under Amendment 86, an off-cycle map would require at least three public hearings and could not be drawn to intentionally favor a political party or unnecessarily divide communities of interest.

What to know

Amendment 86 concerns congressional map changes made between regular census-based redistricting cycles. If approved, it would add commission review, Colorado Supreme Court approval and public-hearing requirements for proposed off-cycle maps.
