Colorado Supreme Court blocks November ballot initiatives to redraw congressional districts

The Colorado Supreme Court unanimously rejected three Democratic-backed ballot measures on June 29, 2026, that would have redrawn the state's congressional map to favor Democrats in seven of eight seats, up from four currently held. The court ruled the initiatives violated the state constitution's single-subject requirement, with Chief Justice Monica Marquez calling the proposal a seismic shift to Colorado's redistricting process. The measures, funded by a group linked to House Minority Leader Hakeem Jeffries and backed by Coloradans for a Level Playing Field, would have temporarily paused the independent redistricting commission voters created in 2018. The decision prevents Colorado Democrats from participating in the national off-cycle redistricting wave that has primarily benefited Republicans, and it is now too late to bring new measures for the November 2026 election.
