The New Deal significantly shifted power to the executive branch by expanding the role of the federal government in economic and social welfare, which increased the authority of the President. President Franklin D. Roosevelt implemented a series of programs and reforms that centralized decision-making and bypassed traditional legislative processes, allowing for swift action in response to the Great Depression. This expansion of executive power set a precedent for increased federal intervention in various aspects of American life, thereby altering the balance of power between the branches of government.
