Yeah. I was in Chicago. My parents had to be registered as Rat’s if we wanted garbage pickup and to avoid the building inspectors. The precinct captain ( whose city job was bridge tender on the Western Ave bridge, which had had it’s motors removed in 1942 to go to a shipyard in Washington state) would come by and show my parents EXACTLY how to vote.
My parents lived in Chicago for a few years before I was born and my dad was a pollwatcher there. He said they literally counted the votes, “Two for us, one for you, two for us, one for you.” The police wouldn’t do anything to stop it.
