Colorado GOP seeks emergency order blocking unaffiliated voters from 2026 primaries

On 2026-04-20, the Colorado GOP asked U.S. District Judge Philip A. Brimmer to issue an emergency order blocking unaffiliated voters from participating in the party’s 2026 primaries. The party argued the request was needed to prevent irreparable constitutional injury after Brimmer’s March 31 ruling on Colorado’s opt-out rules.
