I genuinely believe that if Trump wins, it means the end of Western liberal democracy.
I think it's more like a re-arranging of the chess pieces on the board. America is no longer the worlds sheriff. They gave up that position when they lost in Vietnam and they have been in an accelerating decline ever since.
There are plenty of countries with centrist governments in Europe, some maybe right, some maybe left and that's not likely to change. Similarly here, Australia and Canada. Even our current government is pretty close to the middle ground. Countries sometimes try extremism (eg Brazil and Bolsinaro) but then revert to a more moderate government. The USA will have less and less influence as their decline continues.
