Mail voting is in court.
Updated September 2026
What's happening
The Trump administration is trying to change how mail voting works. Earlier this year, the President signed an executive order directing the Postal Service to verify who gets a mail ballot before delivering it. USPS followed up with a rule that makes that real. Under the rule, the Postal Service stops being your ballot's carrier and starts being its gatekeeper. If you're not on a federal list, your ballot doesn't get delivered.
States, voting rights groups, and party committees have all gone to court to stop it. Courts have blocked the rule more than once. The Supreme Court has now declined to lift those blocks for this election. The legal fight will continue after November.
Your Colorado ballot is coming as planned.
Ballots go out the first week of October, and Colorado's mail voting system is working the way voters built it.

Two federal judges in two different courts have blocked the USPS rule. The Supreme Court let the MA court's block stand. The rule cannot be enforced for the November election. Your ballot is coming as planned.
What we're watching
The Massachusetts cases.
Two cases are in front of the same federal judge who has ruled against the executive order multiple times. Voting rights groups brought one. Twenty-four state attorneys general, including Colorado's Phil Weiser, brought the other. On September 4, she blocked the rule through the November election. The Supreme Court let the block stand.
The DC cases.
Additional challenges are in federal court in Washington, DC. On September 13, a judge issued a separate block on the USPS rule. Two independent blocks from two different courts are now in place.
The big unanswered question.
No court has issued a final ruling on whether the USPS rule is legal. But the Supreme Court said the government is unlikely to succeed on the merits. The legal fight will continue after November. For this election, the rule is blocked.
How we got here
Elections belong to voters.
Coloradans built this system. Nobody in DC gets to override what they chose here.
No politician, no billionaire, no party gets to decide whether your vote counts.
Colorado has to hold. That takes all of us.
