You would expect signs of noncitizen voting in the results. The finding is based on the Cooperative Congressional Election Study, a huge study of tens of thousands of respondents. This phenomenon could explain all of the noncitizen voting in the congressional election study. But this has nothing to do with noncitizen voting, and it is not a meaningful contributor to voter fraud. The political right has not been alone in making unsubstantiated claims about election or voter fraud this year.
