Integrity of Voting Systems Used in Colorado

Hide Featured Image

We continue to maintain confidence in the accuracy and integrity of Dominion’s Democracy Suite® voting system because of the following:

  • Colorado counties began using Dominion’s Democracy Suite® voting system in 2016.  Currently, 62 of 64 counties use the Dominion system.
  • Every version of Democracy Suite® used in Colorado since 2016 was successfully tested by federally accredited Voting System Testing Laboratory (VSTL), to ensure compliance with all applicable federal and state requirements.
  • Colorado counties have successfully conducted six separate statewide risk-limiting audits of paper ballots tabulated by this voting system. Neither the Secretary of State’s office nor county election officials have observed or reported even a single instance of the alleged vote-flipping or vote-eliminating system behavior.
  • We are currently conducting our seventh audit and are confident that it will reaffirm the integrity of the system.
  • Voters should not let unsubstantiated allegations and rumors decrease their confidence in reliable voting systems.

Former Secretary of State, Wayne Williams, Says It Best

“Some folks have asked me about Colorado's voting systems. After an exhaustive administrative, legislative, and legal review, many Colorado counties began using the federally certified Dominion Voting System in 2016. Since its adoption, Dominion machines have been tested in 62 Colorado counties at least 807 times. They have passed every test. 

First, each county in each election uses a bipartisan board to test the voting system prior to using it -- that's a total of 455 pre-election Logic and Accuracy Tests in nine elections. 

Second, in 2017 Colorado began conducting a Risk Limiting Audit after each election. In an RLA, bipartisan teams of judges in each county compare the cast vote record from the Dominion scanners to randomly selected paper ballots (with more actual ballots compared when the race is close). In the six elections since Colorado began RLAs, the Dominion Voting System has passed 352 times. (The other systems used in Colorado also have passed.) And Colorado is in the midst of conducting an RLA for the 2020 general election as well.

So, while I can't speak for the practices of every state (some of whom don't have the procedural protections and audits we do in Colorado), I can state that in Colorado the voting systems we use accurately record the votes of Coloradans -- and we've proved it 807 times.”
