- Widespread Errors: An expanded federal tool for identifying noncitizens on voter rolls is making persistent mistakes, particularly in assessing citizenship for people born outside the U.S.
- Banned From Voting: In Missouri, state officials told local clerks to temporarily ban flagged voters from casting ballots, even though hundreds turned out to be citizens.
- Texas Confusion: As errors emerged in SAVE data, local clerks said the state hadn’t provided them with clear guidance and worried about disenfranchising eligible citizens.



Given that only 22 noncitizens over the course of like 10 years (can’t remember the exact statistic) tried to vote, the way to get the best accuracy would be to just hard code the answer to “yes, they can vote”. Then you get over 99.99% accuracy.
