More than 98% of voters participating in Colorado’s 2024 presidential primary cast their ballot by mail, according to Secretary of State Jena Griswold’s office.

Griswold announced the certification of the election on Monday. The process included a bipartisan canvass board in each county submitting an official abstract of votes to Griswold’s office.

The certified results found President Joe Biden received 477,365 – or 82.45% – of ballots cast by Democratic Party voters and former President Donald Trump received 555,863 – or 63.46% – of Republican Party voters. Nikki Haley, who later dropped out of the presidential race, received 291,615 or 33.29% of Republican votes cast.

Only 1.41% of Colorado voters chose to cast their ballots in person. Slightly more than 98% of Republicans submitted ballots by mail compared to 99.02% of Democrats sending ballots by mail.

“The 2024 Presidential Primary Election was among the most accessible in Colorado’s history,” Griswold said in a statement. “I am proud of our state’s elections and the voting access that we have added over the last five years.”

Active voter turnout was 38.67% in the election as 1.5 million ballots were cast. Colorado has 3.8 million active voters, according to information from Griswold’s office.

There were 562,699 ballots cast by unaffiliated voters in the state, or 38.41% of the total ballots. More than 68% of unaffiliated voters cast Republican ballots and 31% of unaffiliated voters chose Democratic ballots.

Of the remaining 900,000 ballots cast, 27.54% were cast by Democratic voters and 34.04% were by Republican voters.

Griswold’s office reported it worked with county clerks from throughout the state to complete a bipartisan risk-limiting audit to verify the results of the election. When the audit was complete, each county’s bipartisan canvass board approved the results and sent a report to the state.

“I commend the county election officials, election workers, and the employees of the Department of State for their hard work and dedication to delivering great elections for Colorado voters,” Griswold said.
