Some historical context for the recent incidents of voting machines in Democrat-run Illinois and Maryland switching Republican votes to Democrat.
“As long as I count the votes, what are you going to do about it?”
— William Marcy Tweed, (1823-1878). “Boss Tweed” was head of Tammany Hall, the Democratic Party political machine that looted millions in graft, corruption, and open bribery from New York City in the 19th Century.
“Comrades, I consider it completely unimportant who in the party will vote, or how. But what is extraordinarily important is this: who will count the votes, and how.”
— Josef Stalin
So far, there are no reports of “calibration errors” switching Democrat votes to Republican.
