Thats actually your best case, because there isnt any evidence that any illegal voting took place, only mishandling of ballots. Good luck getting said ballots tossed, especially if the voters followed all the rules.
If illegal voting happened in FL (it did) it happened everywhere.
Theres not reason the mox of balloots recieved after the election should be any different than the ones received before it.
The entire democrat house delegation is illegitimate.
