Colorado Voters to Decide on Midcycle Congressional Redistricting Following Supreme Court Voting Rights Ruling
Why It Matters
A recent Supreme Court ruling narrowing the scope of the 1965 Voting Rights Act has reshaped the national debate over congressional redistricting, with Colorado now at the center of a broader Democratic response. The decision has accelerated calls for blue states to redraw their own congressional maps to offset anticipated Republican gains in Southern states ahead of the 2028 election cycle.
What Happened
Colorado voters are set to weigh in this November on a ballot measure that would permit temporary midcycle redistricting — a process that falls outside the standard post-census schedule. If approved, the redistricting would take effect in 2028 and would redraw the state’s congressional map, shifting what is currently a 4-4 partisan split in Colorado’s congressional delegation to a 7-1 Democratic advantage.
The push comes in direct response to the Supreme Court’s ruling on the Voting Rights Act, which critics argue allows states to eliminate majority-minority congressional districts so long as they offer partisan — rather than racial — justifications for doing so. Legal observers note the decision creates significant ambiguity around the line between racial and partisan discrimination in redistricting.
By the Numbers
- 4-4: Current partisan split in Colorado’s congressional delegation
- 7-1: Projected Democratic advantage under the proposed redistricted map
- Up to 15 majority-minority congressional districts — all currently held by Democrats — could potentially be redrawn into majority-white Republican districts nationally by 2028, according to analysts cited in commentary on the ruling
- November 2026: Colorado voters will vote on whether to authorize midcycle redistricting
- 2028: Year the new map would take effect if the ballot measure passes
The Legal Backdrop
The Supreme Court’s ruling has drawn significant attention for its treatment of majority-minority districts — constituencies originally drawn under the Voting Rights Act to preserve the electoral opportunity of Black voters and other minority communities. Under the court’s reasoning, states may redraw such districts along partisan lines without running afoul of federal voting rights protections, provided the stated rationale is political rather than racial.
The practical effect, critics argue, is that Southern states — where Republican-controlled legislatures govern and where roughly half of all Black Americans reside — may now consolidate or dissolve minority-majority seats without legal consequence. Supporters of the ruling contend that race-neutral redistricting is constitutionally required and that partisan line-drawing, while potentially disadvantageous to any group, is legally distinct from racial discrimination. The dispute over that distinction is expected to generate ongoing litigation.
As noted in a recent piece in The Atlantic cited in Colorado Sun commentary, the ruling’s critics have framed its effect this way: actions historically associated with suppressing Black political representation can now be legally defended as routine partisan mapmaking.

Zoom Out
Colorado is not alone in considering midcycle redistricting. Several Democratic-controlled states have begun evaluating whether to redraw congressional boundaries outside the traditional post-census window in response to anticipated Republican map changes in the South. If multiple states pursue this path, the 2028 congressional elections could take shape under a dramatically different national map than the one in place today.
The broader political environment — including ongoing disputes over federal authority, executive power, and constitutional interpretation — has made redistricting one of the most contested battlegrounds heading into the next cycle. Separate constitutional clashes between Congress and the White House have also intensified in recent months. Congress is not expected to pass federal legislation addressing the Supreme Court’s Voting Rights Act ruling in the current session, leaving the policy response to state-level actors on both sides.
What’s Next
Colorado voters will have the final say on the redistricting ballot measure this November. If approved, state officials would move forward with drawing a new congressional map ahead of the 2028 elections. Legal challenges to any redrawn map are widely anticipated. Meanwhile, Southern state legislatures may begin their own redistricting processes, with the full scope of the Supreme Court ruling’s impact on minority representation likely to become clearer as states act and courts review the resulting maps.
