The quota system was set up by Eugene McCarthy and his leftist supporters to break the power of the big city Democrat machines and thus seize control of the party to turn it into a socialist/communist focused political group. their big success was in 1972 when McCarthy was nominated and his rules committee ejected the entire Chicago/Illinois delegation headed by Mayor Daley (richie’s father) and replaced it with their quota organized leftist delegation.
I remember the 1972 election, I remember people in American Indian costumes in the audience.
