Final answer:
FDR referred to Senator Huey Long as the most dangerous man in America due to Long's influential political stance and ambitious 'Share Our Wealth' program that challenged the dynamics of FDR's New Deal.
Step-by-step explanation:
FDR once called Huey Long, a senator from Louisiana and a critic of the New Deal, the most dangerous man in America. Huey Long was a prominent and influential political figure in the 1930s. He was known for his 'Share Our Wealth' program, which proposed the liquidation of large personal fortunes to fund direct payments to less fortunate Americans.
Despite his controversial ideas and questionable math behind his program, Long had a significant following and could have been a contender against Roosevelt for the 1936 presidential nomination if he had not been assassinated.
It promises to give $5,000 to every family and $2,500 to every worker. This ambitious proposal, though criticized for its unfeasible mathematics, amassed a significant following, leading FDR to perceive him as a powerful potential rival in politics.
