Here is an off the cuff list of the best: George Washington, Abraham Lincoln, Grant, Theodore Rosevelt, Coolidge, The war FDR, Eisenhaure, Maybe Reagan, Clinton, Trump.
It is not the man so much as a mix of philosophy, administration and legacy.
To me Lincoln seems like the greatest but at the time he was hated by as many or probably more, than he was loved.
I believe Trump the president was also great.
Trump the man as president…not so much. But it is not clear to me that Trump would have been as successful as he was any other way than the way he was.
That left the opening for a lot of very rapid damage to be done by the following administration when he became a one term president due the to the machinations of the machine.
Why is he hated so much when once he was beloved of the very elites that rabidly snarl at his ankles today? Because he stayed true to himself , he is not, never was, a conservative, he’s an updated 1950’s Anti Communist Centrist Liberal.
He is, as were they in some significant sense, populist and anti elite while connecting to the elite, and he got down and did real work for most of his life. OK executive and then star work, but work of a significant type for many years.
That may be the biggest difference between liberalism of early twentieth century and today…those liberals (even anti communists) were populists of a rather socialist bent who got down and got working guy grubby (which made a lot of those earlier left liberals much more attractive than the modern soy boy type.)
