FBI found that fraudulent voting methods employed by Democrats included:
Preying on the Disabled and Elderly.
As described in the Olinger decision, votes of the elderly and disabled were regularly stolen at the residences where they lived. Their wishes were ignored, and the judges of election, under instructions from the precinct captain, punched a straight Democratic ticket.
Impersonating Absent Voters.
Although the canvass disclosed that a number of persons who were registered to vote in the precinct had died, moved away, or for some other reason had become ineligible to vote, these persons were not struck from the list of eligible voters. Finally on election day the defendants, either personally or by acting through others, caused numerous false ballots to be cast for the straight Democratic ticket.
Registering Aliens.
U.S. Attorney Dan Webb estimated that 80,000 illegal aliens were registered to vote in Chicago.[36] Dozens of aliens were indicted and convicted for registering and voting,[37] and one individual was indicted for recruiting an illegal alien to register to vote.
False Registrations.
Another way to obtain names that could be voted on election day was to have people falsely register to vote in a precinct.
Casting Fraudulent Absentee Ballots.
Precinct captains would ask their workers "to encourage voters to apply for absentee ballots whether or not they had a valid reason to do so and to turn the blank ballots over" so that the captains could vote the ballots.
Buying Votes.
The going rate for a vote in one particular Chicago ward was two dollars, and some precinct captains kept a supply of dollar bills ready on election day solely for buying votes. Alcohol was also used as an incentive to get people to the polls, with one hotel manager ordering "the liquor in advance from the precinct captain.
Altering the Vote Count.
Changing the actual vote count was another method of fraud. For example, one precinct captain and his son held their own fraudulent election after the polls closed by repeatedly running two ballots through the voting machine.
