In September, the office of the Colorado Secretary of State had officially admitted that they had erroneously sent out 30,000 voter registration notices to people who were not US citizens. Best this author could tell that form effectively reminds one that there is an election coming up some time in the future and one needs to register in order to participate in said election. According to the Office of Secretary of State there is no evidence that any of the non-citizen recipients of these notices actually had registered to vote but it is unclear how thoroughly the system tracks the transition from a notice to a registration.
30,000 may not seem like such a large number but there have been elections decided by far fewer votes cast. Overall population of Colorado is about 6 million people thus the number of those erroneous notices constitutes 0.5% of the states total population. A little over 3.1 million people, or about 86% of registered voters, participated in the 2020 Presidential election. In comparison to that count, 30,000 constitutes a little under 1%. That is a significant number.
To be clear, this in and of itself does not constitute evidence of electoral fraud or malfeasance of any kind. It is, however, evidence of extremely poor quality of the data involved. This is an evidence of massive potential vulnerability - and, likely, not the only one.
And this is just one vulnerability, in one state.In light of that, it seems to be far from unreasonable to ask, can any election result be trusted in this sort of environment?
