The data comes from a Harvard/MIT election research organization. A 50,000 respondent sample is hardly insignificant.

I find your own response to be irrelevant to the point made by the Academics. You push for an improved registration process and decry any voter ID as ineffectual without data to support, and then engage in ad hominems against the academics who interpreted the Harvard data.

It is either their or it isn’t, and apparently it is. Could the respondents be lying? Sure, but if they were able to verify that they voted, then it is even more convincing. Unfortunately such records are not uniformly available.

If they applied a percentage corrected for non-citizen distributions it may not be far off, but individual measures by state would have had to had been considered in terms of promoting or disincentivizing immigrants from voting regardless of whether they were here leaglly or otherwise.

I don’t see the issue with the study that you seem to.
