UPDATE: 6:55

Polls will close at 7 p.m. as scheduled. A judge did not honor Colorado Democrats request to keep the polls open two hours longer.

UPDATE 5:30 p.m.

Colorado Democrats are asking for voting hours to be extended by two hours. The Colorado Secretary of State says the move is unnecessary.

UPDATE 5:15 p.m.

There will be a hearing Tuesday night in Denver on whether or not to extend voting hours statewide.

The statewide voting registration system was down for a brief period of

time.

The voter registration was done for about 30 minute.

The Secretary of State's office says clerks could not process mail in ballots that need to have the signature verified. They also say in person voters had to vote provisional. If that has been down, they can continue.

The incident is being investigated.
