The New Deal transformed American politics by expanding the role of the federal government in economic recovery and social welfare. It introduced a series of programs and reforms that aimed to alleviate the effects of the Great Depression. This shift fostered a stronger relationship between citizens and the government, enlarging the Democratic Party’s base and redefining political alignments. The New Deal's influence has since persisted, impacting policy ideologies and expanding government responsibility for economic and social issues, thus reshaping the political landscape for decades.
