The thing that's most dispiriting about the 'vote dump' charts (which purport to show irregularities, but just show large Dem. cities reporting), is that it's in such complete bad faith that there's no way the electoral process could be reformed to guard against it going forward
Take mail voting, for instance. If you wanted to restore the credibility of the electoral process, you could eliminate no-excuse mail voting on the grounds that it's no longer credible to a wide swath of the electorate, even if you thought their concerns were completely wrong
The 'vote dumps,' OTOH, are an inevitable artifact of how jurisdiction reports their votes in batches, rather than updating their tally vote by vote. There's really nothing you can do to avoid this. Taking issue with it just means you don't believe election results, period
It's particularly remarkable in this case because the jurisdiction in question--Milwaukee--was transparent about how exactly many mail ballots they had to tabulate and when they would be tabulated. There was zero surprise. It's also how they've always done it, including in 2016
True, this would eliminate 'dumps,' but it would give rise to a new set of conspiracy theories. At a certain point, if you want to reject an election result you'll contrive a way to do it. The 'dumps' argument make it clear we're in that category https://twitter.com/RandomMusings15/status/1329768266559090694?s=20
