Final answer:
Franklin Roosevelt's 1932 presidential campaign was not a complete break from Progressive ideas; his New Deal was an extension and expansion of Progressive principles, aiming to use federal government intervention to provide relief and economic recovery.
Step-by-step explanation:
The statement that Franklin Roosevelt argued that the New Deal would serve as a decisive break from the principles and ideas of his Progressive predecessors is False. Roosevelt's campaign for president in 1932 did indeed represent a departure from predecessor policies in terms of scale and federal involvement, but it was still firmly rooted in Progressive ideology advocating for greater government intervention in the economy and social welfare. His campaign pledges focused on the promise of the New Deal, which built upon Progressive ideas and sought an active role for the federal government in providing relief and economic recovery. The New Deal was not a complete break from Progressive ideas but rather an extension and expansion of them to address the economic crises of the Great Depression.
