You can’t say there is no evidence of election fraud.
The anonymous Twitter feed this story reports on has been getting some attention. The feed claims: “It appears Dems shot themselves in the foot [because] making everyone do mail-in ballots actually makes it easier to catch mail-in ballot fraud. [Because] all of the ballots go through the postal system, they get shuffled like a deck of cards, so we expect reported ballot return[s] to be extremely UNIFORM in terms of D vs R ratio, but to drift slightly towards R over time [because] some of those ballots travel farther [from rural R precincts to the counting centers in D cities].”
The Twitter feed’s caveat is important: “while anomalies are not always fraud, often they may point to fraud.”
The basic claim looks plausible to me, but I’d like to see some peer review.
