Thought experiment: Imagine if Donald Trump had the skill to wield the powers of the office that FDR possessed.
I'd settle for what LBJ had in 1964! Johnson was another of the SWAMP creators as his "War on Poverty" & "Civil Rights Act" did much to move power to Washington over the States.
Was it as much FDR’s skill or what is that he had the cooperation of the bureaucracy? From the perspective of a bureaucrat he are you going to help and who are you going to resist? Obviously you are going to support the guy who is giving you more power and prestige and do everything in your power to thwart the guy taking away power and authority.
Trump lacked insider skills and knowledge, but he also had much of the government apparatus working against him. If he was working to expand their power they would have loved him and made him look like the greatest president ever.
