WASHINGTON, D.C. — On Tuesday evening, the Colorado Independent Legislative Redistricting Commission approved the map for state Senate districts, one day after approving the state House map. After making changes earlier in the evening to reach an agreement, the state Senate proposal gained unanimous support, while the state House map was approved 11-1. Colorado voters passed Amendments Y and Z in 2018, reforming the state’s redistricting process and handing the map drawing power to a selection of 12 volunteers from across the state. The commission is composed of four Democrats, four Republicans and four unaffiliated commissioners, and advised by nonpartisan staff.
The new state House map has at least 16 incumbent representatives who would now live within the same district as another. Eight state Senate incumbents would face a similar situation, forcing them to make the decision to run against a colleague or change addresses, as Colorado requires lawmakers to live within the district they represent. However, Democrats are expected to maintain their majority in both chambers. The maps now advance to the state Supreme Court for final review. The Colorado Supreme Court is currently reviewing the state’s congressional map, which was advanced by the Congressional Redistricting Commission two weeks ago and has faced criticism in court.
