Very early on in the discussion of how this happened, people like Mike Lindell, Sidney Powell, General Michael Flynn, Patrick Byrne and others seized and held attention for months as they focused much of the population’s attention like a laser on the Chinese hacking theory.
All that activity culminated in two embarrassing fiascos:
It may be that instead of relying on electronic manipulation of vote totals by hackers in China or some other foreign venue to steal it for Joe Biden, the Democrats relied on the old tried and true method that has served them so well in the past: good old-fashioned ballot box stuffing.
But the same month that Lindell’s Cyber Symposium ran off the rails, there was another development that received little attention at the time.
It was in late August of last year that the group True The Vote was revealed to have been buying and collecting and sifting through trillions of commercially available cell phone tracking signals as a means of tracking ballot box stuffers [who are commonly referred to as ‘mules’].
The document says that True The Vote has spent the last several months since late last year collecting more than 27 terabytes of geospatial and temporal data—a total of 10 trillion cell phone pings—between Oct. 1 and Nov. 6 in targeted areas in Georgia, Arizona, Michigan, Wisconsin, Pennsylvania, and Texas. The data includes geofenced points of interest like ballot dropbox locations, as well as UPS stores and select government, commercial, and non-governmental organization (NGO) facilities.
“From this we have thus far developed precise patterns of life for 242 suspected ballot traffickers in Georgia and 202 traffickers in Arizona,” True The Vote’s document says. “According to the data, each trafficker went to an average of 23 ballot dropboxes.”
In other words, what the document says is that True The Vote was able to take cell phone ping data on a mass wide scale and piece together that several people—suspected ballot harvesters—were making multiple trips to multiple drop boxes, raising potential legal questions in a number of these states.
