Amendment 84: Mail Ballot Voter Identification
Source: results.enr.clarityelections.com
What does this measure do?
Voters would have to write the last four digits of their Social Security number or their Colorado driver's license or ID number on the mail ballot envelope, next to their signature. A ballot missing that number would not count until the voter fixes it, and elections would cost more to run.
Proposed by: Citizen initiative by the Colorado Voter Trust Initiative (Chuck Broerman and Suzanne Taheri)
Broerman is El Paso County treasurer; Taheri is a former deputy secretary of state. Out-of-state groups fund it, led by Ohio's Coalition for American Prosperity and Growth ($2.25 million).

A YES vote means
Every mail ballot needs a signature plus an ID number on the envelope. Ballots without a matching number are set aside until the voter fixes the problem.
A NO vote means
Mail ballots keep working as they do now: a signature check only, with no ID number required on the envelope.
