Subject: Re: Mail-In Ballot Trickery in Pennsylvania
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.

To be a little more specific, though, 2020 was an election year where many of the rules regarding mail-in ballots changed. A lot of the Covid-specific accommodations resulted in a significant increase in the number of folks using mail-in ballots as their method of voting. It was widely expected (and turned out to be the case) that you would see many more Democrats voting by mail than Republicans, given the partisan and geographic skew on attitudes towards Covid. So this was a case where past performance was not likely to be indicative of future results.
