Rejecting undated mail ballots disproportionately impacts communities of color in Pa., data shows

3. Are voters in districts with higher minority populations more likely to vote by mail?

That would make sense if that was the case. Other than that; why?

The article never really says why the percentage of rejected ballots is higher in areas with a higher minority population?

They do mention that those areas trend a little older, but that doesn't really explain why people were unable to apply a proper date on a mail in ballot? The study says that since they actually have no idea of the racial make up of those who mailed in flawed ballots, that they can only surmise based on zip codes only. In addition, the number of rejected ballots overall is quite low and the study only covers three larger counties, so any smaller rural counties are omitted from the study.
