This is commonly known in west Texas and Chicago. To be honest, from national to city-type elections...I doubt if any of them are totally free of corruption.
Another good example is the SF city mayor recall election election of 83 (Mayor Feinstein defeated this with 81-percent of the vote) is commonly believed to be rigged.
The 1973 SF mayor election (Mascone versus Barbagelata) was heavily screwed by the Jim Jones ‘sect’ (coming in from outside of town to vote).
It wouldn’t shock me if 10-percent of Hillary’s votes in 2016 were corrupted. You find any state where there’s only 3 or 4 percentage points of difference....then you go and buy the votes to swing things.
No doubt that Illinois was stolen but Texas alone would have been enough stolen. JFK would have won without Illinois’ electoral votes.
Thats the 1975 San Francisco election.
