DENVER -- Residents and college students who registered to vote in Boulder County by the Monday deadline, but did not correctly complete a Colorado voter registration form, will have extra time to clear up any issues with their registration, the Clerk and Recorders Office said Monday.

The Clerk and Recorders Office will send letters to people who need to correct their registration information. They will have until Election Day to complete their registration, said Jessie Cornelius of the Clerk and Recorder's Office.

“Voters who are notified should complete their registration information with the form they are sent and return it to our office as soon as possible,” said Boulder County clerk and recorder Hillary Hall. “We want to ensure registrants know they can still correct their information and participate in the general election on Nov. 4.”

Friday, the University of Colorado student union sent out an e-mail asking students to double check their registration status saying many did not check the box on the form.

“A lot of us think we’re registered, and we’re not,” said Ida Ghebre, a CU student who said she registered to vote on campus. “Yesterday, I checked the link and I wasn’t registered and I don’t know why.”

UCSU Tri-Executive Ryan Biehle said he kept hearing the same story from various students.

“We wanted to make sure students were aware this could be a problem,” he said.

He believes the problem is because many students don’t have a Colorado driver’s license, so they gave their Social Security number instead, and forgot to check the required box.

Registrants who have a Colorado driver’s license or Department of Revenue Identification Number are required by law to provide their ID number on their voter registration form.

Voters who do not have these forms of ID are required to check the box indicating, "I do not have a Colorado Driver’s License or Department of Revenue Identification Number."

Voters would then need to provide the last four digits of their Social Security number.

“I think this gets to the broader issue of complicated voter registration system that’s out there. In this state, we need voter registration reform,” Biehle said.

It is not known how many students incorrectly filled out their forms. The clerk and recorder said it is mailing 1,700 letters to registrants who did not complete their form correctly.

Voters are encouraged to check their voter information on VoteBoulder.org to ensure they are registered to vote.
