Kyle is owning the socialism brand.
American populism has never been socialism.
Populism has always been rural, socially conservative, grounded in evangelical Christianity and republicanism and descends from the Jeffersonian-Jacksonian tradition. Populists don’t like concentrated economic power or extremes of wealth that give elites too much power over the masses. Populists are moderates on economics, but have no problem with private property.
Socialists tend to be college educated libtards who are atheists who live in big cities on the coasts who believe in all kinds of absurd shit. Their brand is extreme social liberalism, enormous government spending programs that harm the working class and middle class and interventionism abroad.
Note: Bernie Sanders is pro-war in Ukraine, pro-spending trillions of dollars on government programs that employ struggling college graduates and pro-cultural degeneration.
