Were people voting more than twice? Four five six seven times?
Also depicted in the movie were more votes then populous/ballots. Was that sort of thing common?
Experts in voter fraud at any time are welcome to answer this question. I'm sure each period has its own different voter fraud tactics. I am interested to know how many votes the average person voted, how many votes someone could get away with, dead voters, suppressed voters, forced voters, the rich swaying elections (paying voters/delagatrs) and anything else unusual or interesting.
Sorry if this is too wide. Feel free to let me know a better way to ask or if I should focus on an era. I'm happy to edit the body for more focus.
There have been various ways in which political machines got their votes. But although getting somebody to "vote early, vote often" did happen, they soon realized that the most efficient way to steal an election was when the ballots were counted: it was a lot of work to get each individual voter out, and since their votes were secret, it was impossible to make sure they'd actually voted the way they'd been bribed. Much easier to add ballots at the count, lose ballots at the count, or even lose entire ballot boxes. Fewer people were involved, too, to keep it secret. ( And yes, this has also been one of the criticisms of the voter ID laws in the US: they address a problem that has not really existed.)
Still, there's a lovely scene in The Secrets of the Hopewell Box, a history of the political machine in Nashville TN in the 1950's, where the party boss is driving through town at the head of a long convoy of brewery trucks on election night after the polls had closed, stopping at every precinct corner and signalling the drivers as to how many cases are to be placed at the feet of each precinct captain, for having delivered his precinct. Ah, the good old days.
