How they rigged the 2020 presidential election

From today, in hindsight, it seems much more plausible that the voters wanted to keep Donald Trump in the White House instead of replacing him with Mr Biden. Evidence of election fraud is so overwhelming, from so many places and under different perspectives, while the margins of supposed "victory" for the Dems are so small …
it comes down at its core to little more than 100 k votes in some metropolitan areas with about 3 m people. Corrupt places that have been under complete Dem control for decades. Add to that a whole number of more obvious shenanigans that rigged the election outcome.
The official outcome couldn't be changed (as court cases were dismissed out of formal reasons after the election…).
But election integrity has to be secured for the future. 2020 must not happen again. And this ought to be a bipartisan common sense position, too.

This video presentation can be a starting point for anyone seriously interested in the matter. Also, new evidence is coming out almost on a daily basis.
