On Friday, July 24, Colorado Secretary of State Jena Griswold certified the statewide 2026 primary election, making the results of the election official and final.
“Today’s election certification concludes the statewide 2026 Primary Election,” said Griswold on July 24. “I want to thank county clerks and election workers for their work. We will continue our work to ensure Coloradans can make their voices heard in the 2026 General Election.”
After Election Day, the Secretary of State’s Office worked with Colorado’s county clerks to complete a bipartisan post-election audit that verified the results of the election. After the audit, each county’s canvass board certified the election results. The canvass boards then submitted the final results to the Secretary of State’s Office.
