“In Colorado we do fishing, hunting, and hiking better than anyone. We do elections that way too. It's why Colorado has some of the most secure elections in the country. Amendment 84 will keep it that way. Amendment 84 protects your vote by making sure every ballot is matched to the right person. We already show an ID to do what Colorado does best. Amendment 84 helps us level up our elections too. Vote yes on Amendment 84.” - Colorado Voter Trust Initiative 

"Forget the number, miscopy a digit, or skip the field — and election judges are required to reject your ballot unless you complete a cure in time. Elderly, disabled, and first-time voters are most exposed: every added step and deadline is another chance for a valid vote to go uncounted.

Return envelopes pass through hundreds of hands — postal carriers, sorting facilities, ballot-processing teams. Writing an SSN or driver's license number on an envelope clearly marked as a ballot is a flashing target for identity thieves. Discarded envelopes only widen the risk.

Older voters, rural voters, low-income voters, and voters with limited English proficiency rely most on mail ballots — and are most likely to be tripped up by a new, surprise requirement. The result: lower participation, with no security gain.

You already provided your SSN or driver's license number when you registered. The state already verified it. Colorado then checks every returned ballot with a signature match — a biometric tied to you alone. Writing a number on the envelope adds nothing but error and exposure." - Defend Our Ballots
