In the documentary, they used two different bars that had to be crossed to determine if someone was a mule:
The highest, and most restrictive bar specified that a user had to pass the site of at least one Non-Profit, and pass up to 10 ballot drop boxes. In this scenario, assuming those ballots were for Leftist candidates and discounting those ballots (a valid assumption) resulted in a Trump win.
If they lowered the bar and specified that a user had to pass the site of at least one Non-Profit, and pass up to 3 ballot drop boxes, this scenario, (again, assuming those ballots were for Leftist candidates and discounting those ballots) resulted in a Trump landslide.
They make the point repeatedly that it doesn’t take a lot of votes to swing an election, it takes a smaller number of votes in the right places to do so.
No, the mules had to visit FIVE non profits.
