I believe the numbers are something like 11,000 or 17,000 at one time. And I have also seen mentioned 6,000. Do that ten times, and four of these elections flip to Trump.
Any block of votes electronically changing would warrant a 2nd election if I were a Supreme. I do not believe it true that one can fully audit such chicanery.
If Biden is installed as POTUS, and he shuts the country down, this country will come as close as it ever has to an armed insurrection as it ever has in its history. And to make matters worse, his decisions will send the country into perhaps a 2nd depression.
