Online voter registration in Colorado saw a significant increase following the presidential debate between Vice President Kamala Harris and former President Donald Trump, according to the Secretary of State’s Office. 

More than 21,000 Coloradans either registered to vote for the first time or updated their voter registration on the day of the debate and in the days that followed.

“Registering to vote is the first step to making your voice heard in our democracy,” said Secretary of State Jena Griswold. “It is exciting to see Coloradans registering to vote and getting involved in advance of this November’s election. Every voter has a voice, and I’m proud to make sure that every Coloradan can be heard.”

Before the Sept. 10 debate, the Secretary of State’s Office saw an average of 1,604 voter registrations and updates every day in September. 

On the day of the debate, nearly 4,500 voters registered or updated their registration, with more than 1,000 registering during the debate itself. An additional 900 voters registered after Taylor Swift’s social media post encouraging her followers to visit vote.org.

The day after the debate saw nearly 5,000 registrations and updates, and on September 12, the day Meta launched its voter registration banner on Instagram, Facebook and WhatsApp, nearly 12,000 Coloradans registered or updated their registration. 

An additional 11,300 Coloradans registered or updated their registration on September 17, which is National Voter Registration Day. 

As of Sept. 19, there were 3,906,892 Coloradans registered to vote. Of those, 26% are registered Democrats, 23.2% are registered Republicans, and 48.6% are unaffiliated.
