When machine parties were at their height voter turnout was what?

During the height of machine politics in the early to mid-20th century, voter turnout in many urban areas often reached significant levels, sometimes exceeding 80%. Political machines, particularly in cities like Chicago and New York, mobilized large numbers of voters through various means, including patronage and community engagement. This high turnout was often driven by the machines' ability to organize and incentivize participation, though it also raised concerns about electoral integrity and corruption.
