The Colorado Supreme Court on Monday rejected three proposed ballot measures that would have altered the state’s congressional redistricting process ahead of the 2028 elections. The measures, backed by a group called Coloradans for a Level Playing Field, sought to temporarily suspend the independent redistricting commission that voters created in 2018. They also would have let voters approve a new congressional map for the 2028 and 2030 election cycles.
Two companion measures aimed to pause the commission and set new district boundaries as separate initiatives.
Had the proposals qualified for the November ballot and won voter approval, the revised map would have taken effect for the 2028 elections. Supporters said the changes were needed to redraw district lines. Opponents countered that the measures would have significantly reshaped the state’s current redistricting system.
Court Finds Violations of the Single-Subject Rule
In three separate opinions, the court ruled that each proposal violated the state constitution’s “single subject” requirement, which bars a ballot initiative from covering more than one topic. That finding kept all three from advancing, according to NBC News.
Chief Justice Monica Marquez wrote in a unanimous decision:
“Changing the constitutionally mandated frequency of redistricting — however temporary the change — is not merely a mechanism to administer the new congressional district map.”
“Instead, it represents a seismic shift to Colorado’s longstanding redistricting process enshrined in the state constitution,” her opinion added.
In a second unanimous opinion, the court concluded that splitting the original proposal into two separate ballot measures did not cure the problem, because the revised versions still failed the single-subject requirement.
A spokesperson for Coloradans for a Level Playing Field did not immediately respond to requests for comment on the rulings.
A Broader National Battle Over Mid-Decade Maps
The Colorado case unfolds against a wider national debate over redrawing congressional districts in the middle of a decade. The issue gained momentum last year when President Donald Trump urged Republican-led states to consider new maps that could widen the GOP’s narrow majority in the U.S. House of Representatives.
Democrats have faced added obstacles in states such as Colorado, where independent commissions control the map-drawing process.
Virginia Democrats pursued a similar strategy this year with a ballot measure that would bypass the state’s independent commission and adopt a new congressional map. Voters narrowly approved the proposal, but the Virginia Supreme Court later blocked it from taking effect, NBC News reported.
The decision left House Democratic Leader Hakeem Jeffries facing sharp criticism. Republicans accused Democrats of overreaching in a high-stakes redistricting fight that ultimately collapsed in court.
In a 4-3 ruling in May, the Virginia Supreme Court invalidated the voter-approved map. The justices found that Democratic lawmakers had violated procedural requirements in the state constitution when they placed the referendum on the ballot.
The ruling requires Virginia to redraw its congressional districts before the 2026 midterm elections. It also erased what Democrats had hoped would become a 10-1 advantage in the state’s congressional delegation, marking a major setback in the broader redistricting war between Republican- and Democratic-led states.
Before the ruling, Jeffries had strongly defended the effort and argued that Democrats had a solid legal footing.
“The law is with us in Virginia,” Jeffries said while promoting the plan.
That statement drew renewed attention after the state’s highest court sided with Republican challengers and blocked the maps.
Republicans Hold the Upper Hand
The Virginia and Colorado cases come as a nationwide redistricting battle accelerates ahead of the 2026 elections. Republicans appear poised to enter November’s midterms with a significant advantage from redistricting efforts across the country, as a coast-to-coast fight over congressional maps nears its conclusion.
The struggle began last year when Texas Republicans, encouraged by President Trump, moved to redraw their congressional districts to strengthen the party’s position in the U.S. House. Since then, both parties have pursued increasingly aggressive efforts to reshape congressional boundaries, but Republicans currently hold the upper hand.
