Final answer:
Political machines in America perfected their system before immigrants came by controlling elections through bribery, fraud, and intimidation of voters. They formed alliances with business and labor leaders to maintain power and rewarded loyal voters with jobs. Tammany Hall in New York City was one example of a political machine that used corruption to control politics for several decades.
Step-by-step explanation:
America's political machines perfected the system through various tactics before immigrants arrived. One key tactic was the control of elections through bribery, fraud, and intimidation of voters. Political machines offered small bribes to impoverished voters in exchange for their support.
They also formed alliances with business and labor leaders, which allowed them to reward loyal voters with jobs and provide social services. One example of a political machine was Tammany Hall in New York City, which controlled politics through corruption from the 1850s to the 1930s.
