I'll say again unless the voting process is greatly improved, and mail-in ballots are done away with, this type of shit show will become a regular thing.
You cannot have counting of any kind post-election day. It's that simple. The actual counting of votes needs to be more transparent.
I stated before I'm in favor of early in-person voting because that benefits the entire electorate and both parties as it allows more people to vote.
However, with early voting, there is no reason votes can't be counted by end of the day on election day.
I said it before and I'll say it again, wear your reps out at every level about more efficient, secure, and timely voting.
