Subject: Re: Mail-In Ballot Trickery in Pennsylvania
I'll try to look, but I'm really only finding more recent stuff about mail-in ballots. As albaby said, old tends to equal conservative, and elders like mail-in ballots. And I don't remember now if they also included overseas service members, but most serving lean conservative.

If I do find an article circa 2020, I'll post it. That's when the Reps started kicking up a fuss, and I remember on TMF they were being ridiculed because the data showed that mail-in ballots favored the Reps.
