Probably like-minded authoritarians, such as Woodrow Wilson, Franklin Roosevelt, Lyndon Johnson, Richard Nixon, and, to a lesser extent, Ronald Reagan.
LBJ had too much respect for actually reading the rules and methodically reading people to withstand someone so random like Trump.
Also, no F&*(ing way the guy who taught Mexican immigrants English would think highly of Trump.
... Johnson was a nationalist in all but name, and he did what he did for political purposes. He wasn't some "morally superior" modern Democrat.
