Boulder County Voters:
This page is to track and provide brief updates on what is happening with federal legislation and executive actions that could impact voter registration, voting procedures, and voter data.
Sept. 3 Update
As noted below, on Aug. 27 a federal court blocked the USPS from implementing its new mail-ballot rules. Today, the Trump Administration formally asked the U.S. Supreme Court to review that temporary order, which would allow the USPS to move forward with the proposed changes.
The Supreme Court is expected to respond to the request by 10 a.m. on Tuesday, Sept. 8. We will await that decision and provide any new updates then.
Currently, we expect our mail ballot process in Colorado to proceed as normal. However, please know that our office is prepared to ensure a successful, transparent, and fair election under any circumstances.
Aug. 31 Update
There have been several significant developments since our Aug. 25 update regarding President Trump’s executive order and the federal government’s efforts to impose new requirements on mail ballots.
The most important takeaway for Colorado clerks and voters remains simple: Colorado’s current mail-ballot procedures remain in place, and no operational changes are required at this time.
Formal USPS Rule Adoption and Challenges from States and the League of Women Voters
On Aug. 21, the U.S. Postal Service formally adopted a new rule implementing portions of President Trump’s March 31 executive order regarding mail ballots.
On Aug. 26, Colorado Attorney General Phil Weiser joined 25 other states in filing a new lawsuit challenging the USPS rule. The states argue that USPS does not have the authority to impose these requirements on states.
The League of Women Voters and other voting-rights organizations have also continued their separate lawsuit challenging the federal government’s authority over mail voting. After USPS published its final rule, the League amended their complaint to specifically challenge the now-final USPS rules.
A federal court has now blocked USPS from implementing the new rule
On Aug. 27, a federal judge issued a temporary order blocking USPS from implementing the new mail-ballot requirements. The court found that there was not enough time to make these changes before the November election.
The temporary restraining order is currently in place for 14 days while the court is considering whether to issue a longer-lasting preliminary injunction.
What about the Supreme Court decision?
The Aug. 24 Supreme Court decision has not been overturned.
The Supreme Court overruled a decision that had temporarily stopped USPS moving forward with proposed rules. At the time, the rules were not yet final, and this was a procedural decision, not one that is based on the merits of the rules.
The circumstances have now changed because USPS has issued its final rule and new litigation is directly challenging that rule.
Bottom line
The new USPS mail-ballot requirements are currently blocked from implementation for the 2026 election. Colorado clerks do not need to redesign ballots, change mail-ballot procedures, or begin using the new USPS portal at this time.
For voters, the same message applies: your ability to receive and return a Colorado mail ballot has not changed. County Clerks will continue administering the 2026 election under Colorado law and established procedures, and will communicate promptly if any court decision or federal action requires a change.
