During David Dinkins’ bid for reelection, they bused retarded adults to the polls and promised them to go bowling afterwards. The polling place was full of addled adults saying “bowling! bowling!” as they were guided to the voting machines. And that was a relatively honest election year, long before ACORN.
Fortunately, Dinkins still lost that election, although it was close.
BTW. there are no more of those "classic" voting machines with levers that are pulled in NYC. They have now been replaced by by paper ballots - in AT LEAST FIVE DIFFERENT LANGUAGES! (That makes the paper ballot much larger than it has to be.) The voter fills in a circle or oval next to a candidate's name and then inserts the completed ballot into an optical scanner. If there's some trouble with the scanner, a poll worker might help out by inserting the ballot. If the ballot is not scanned correctly, the voter will never know.
