these 3 examples you choose as "real leaders" are merely demagogues.
simplistic solutions to popularly acclaimed problems, solutions that won't work. these 3 are stupid people who are smart.
I'll give you a few examples from Aus of real leaders:
Menzies
Curtin/Chifley
Howard
Gillard
Albanese might become a real leader but I seriously doubt it. the remainder were either fools who climbed the greasy pole of ambition via the Party Ladder or didn't last the distance to become real leaders. Holt was one who could've been.
