Well, votes misaligning beyond statistical possibility in one "category" of counties, with absolutely no statistical anomalies in another "category" of counties is irrefutable proof, mathematically, that something is wrong.

Ex: if specific counties that use a particular tool have a massive mismatch between presidential voting and senate voting, but there is absolutely no spread in similar-politically counties that use different election tools, then the only possible explanation is that the tools affected the results (i.e. "fraud").

I believe that's the evidence, from what I understand.

Now, there are people coming forward in large enough groups saying they all voted for a particular candidate in total numbers of people larger than the were total votes recorded t that candidate at that polling station, including reports of 0 votes for Kamela with voters reporting she wasn't on the ballot for them. So that might give a new "lever" for investigation.

Regardless of election fraud, though, the election results are already certified; at this point, Trump is president, and even definitive proof of fraud won't change that. What it could change, if the current Republican authoritarian government allows it (lol), is oversight and regulations at future elections.

Or, perhaps, the blatant corruption will lead to states seceding from the union.

American hegemony and global dominance is over, but how it falls apart is yet to be determined.
