Reply #13: All Presidents argued for it in the abstract...

[Zimmy44]

...but only one President took what was a theoretical debate between the different branches of government and actually acted on it. All Presidents would argue for expansive authority, and would feel it's their duty as the holders of the office not to agree to limits on its powers. But they would have also felt constrained not to put the theoretical powers into actual use. There's a reason the paper was 'little noticed' - it didn't really mean anything in practice.
