DENVER–The Colorado Supreme Court on Monday hit the brakes on a trio of Democrat-backed ballot measures that would have torn up the state’s congressional map and handed Democrats seven of Colorado’s eight U.S. House seats, leaving Lauren Boebert’s 4th Congressional District as the lone GOP seat.
The measures, pushed by a group called Coloradans for a Level Playing Field, would have temporarily blown past Colorado’s independent redistricting commission, which voters created in 2018 specifically to take map-drawing out of partisan hands, and installed new congressional districts for the 2028 and 2030 elections.
The group tried two approaches, with Initiative 240 packaging the whole scheme together. Two other initiatives (241 and 242) tried to split it into separate pieces that would only take effect if voters approved both. The high court said neither trick survives the state constitution’s single-subject rule, which bars bundling unrelated changes into one up-or-down vote.
Justice Richard Gabriel didn’t mince words on the interlocking-measures gambit: “When a measure’s effectiveness is expressly contingent on the passage of a separate and independent measure, the measure contains multiple subjects, just as if the measures were combined into one.”
Chief Justice Monica Márquez was equally blunt about the standalone version, calling a temporary suspension of the redistricting commission’s authority “a seismic shift,” noting some voters might support moving up the timeline for redistricting without backing the Democrat-favoring map, while others might like the map but not the precedent of mid-decade changes, exactly the kind of mixed issues the single-subject rule is designed to prevent.
Coloradans for a Level Playing Field claimed to have gathered tens of thousands of signatures toward the roughly 125,000 needed per measure, apparently betting the court would let the maneuver through. Out-of-state funders backing the effort include House Majority Forward, a group tied to U.S. House Minority Leader Hakeem Jeffries.
The Colorado gerrymandering push comes amid a nationwide mid-decade redistricting fight kicked off by Texas Republicans at President Trump’s urging, which could net the GOP up to five additional House seats, followed by a retaliatory California map that could hand Democrats five seats of their own. According to the National Conference of State Legislatures, ten states have now completed mid-decade redistricting, with courts intervening repeatedly — striking down a Democratic map in Virginia while upholding a Democratic-leaning redraw in Utah.
The ruling keeps Colorado’s voter-approved redistricting commission intact and out of the national gerrymandering scrum, at least for now.
