Immigrants in cities became new voters in large numbers primarily due to their growing population and the increasing importance of urban political machines, which actively sought their support. These machines often provided essential services and assistance to immigrants, fostering a sense of loyalty and encouraging them to participate in the electoral process. Additionally, as immigrants sought to secure their rights and improve their living conditions, voting became a critical means of influencing local policies and representation.
