The ballot question
Shall there be an amendment to the Colorado Constitution requiring a voter to sign and include the last four digits of their social security number or their Colorado driver’s license or identification card number on the outside of their mail ballot for any federal or state election, and, in connection therewith, allowing the voter to correct missing or incorrect information, including with alternative forms of identification; and prohibiting a county clerk and recorder from counting the mail ballot unless the problem is fixed?
What a vote does
- A yes vote means
- Section 13 is added to the Colorado Constitution. In federal and statewide elections a voter must sign the mail ballot self-affirmation and write an identification number on it. A clerk may not count the ballot until a missing or unmatched entry is corrected.
- A no vote means
- The measure is not enacted. No section is added to the constitution, and the signature and self-affirmation rules for returning a mail ballot stay as current law sets them.
