I don't mean to de-rail the thread but I hear references that the Republicans stole Ky. in 1960 and that the Democrats stole Il.
How was this supposed to have taken place?
The easiest way to cast fraudulent ballots without getting caught is voting multiple times for different dead people. Since there is no voter ID, and poll workers may or may not know you. A political boss will give you a List of deceased people from different parts of town. So you just go to 10 or more polling stations and vote as the deceased person.
Or they can just circumvent the voters, and manipulate the voting machines, ballots, or poll-counters in some fashion - but that may be easier to get caught.
