I just downloaded Trump's appeal brief. Essentially:
1. The court should have let us amend our spurious claims in the lawsuit caused by us going off half-cocked as usual.
2. We didn't mean to disenfranchise 6.8 million Pennsylvanians, just 1.5 million of them who voted for Biden.
The latter is spurious, because as the size of the disenfranchisement was just hyperbole in the decision. The arguments were that the two exemplar voters were not offered the right to cure their incomplete absentee ballots in one county, so all such cured ballots must be discarded. The court pretty much ruled, that the operative remedy (if one were required, which the decision points out is unproven), would be to cure the ballots not coutned, not to disqualify a bunch of supposed "similarly affected" ones.
