In searching to find out how various regions of the Hawaii islands voted in 2020 (some are far more conservative than others) I came across a very curious statistic :
In many areas, in person voting went 75-25 for Trump, while the mail in votes were the opposite at 75-25 for Bidet*.
Never found any explanation for how the choices could be so upside down.
You mean like Pennsylvania, Michigan, Wisconsin, and Georgia? (I think I left out one or more.)
