As I explained earlier today, "absentee" is not "mail-in." Absentee is a pull system, where voters request a ballot.
States like CO which had "push" mail-in ballot distributions had scrubbed their voter lists to minimize fraud. States which did not have scrubbed lists for such push systems, yet sent out ballots anyway, are what I am calling "shotgunning."
I realize that most people don't understand these nuances so I'm about done with this discussion.
