Dinesh D'Souza's film, 2000 Mules, was just released, and it is jaw-dropping. The level of questionable practices and outright cheating is staggering. To oversimplify: Using high-tech forensic geolocation, cell phone information was collected that proved that ballot drop-offs at multiple boxes miles apart by the same "mule" were in progress. A mule is a paid or unpaid person who (in this case) drops illegal ballots off at these drop boxes.
D'Souza's team set the bar to determine fraud deliberately high so that results of this investigation could not easily be questioned or passed off as mere coincidence. Stringent criteria were set up so that video evidence of highly suspicious drop box activity would be easily verified by unbiased parties. D'Souza was inordinately careful so that his film would not be dismissed or ridiculed by rational people. The purpose was not necessarily to claim that Trump won and Biden lost. The purpose was to demonstrate how easy it is to cheat and that cheating did indeed take place in the 2020 election.
