Polls have closed in Colorado following a judge’s denial of the Colorado Democratic Party’s request to extend voting by two hours. The polls closed as scheduled at 7 p.m.

Head of the Colorado Democratic Party Rick Palacio argued polls should have been kept open to account for a 29-minute computer glitch Tuesday afternoon. The statewide glitch affected same-day voter registration and caused some voters to have to cast provisional ballots, and some county clerks were unable to process mail ballots that needed to have the signature verified.

The Secretary of State opposed the extended hours. Deputy Secretary of State Stephanie Staiert says no one was prevented from voting because of the glitch.

Democrats suspect the outage was caused by an external intrusion into the state’s voting system.

The spokeswoman for the secretary of state originally said Democrats wanted to keep polls open 25 minutes, but the Democrats instead sought two additional hours.

Lynn Bartels, a spokeswoman for the Secretary of State’s Office, tweeted that the system goes down now and again. She said the Secretary of State’s Office is investigating the cause.
