You need to study up on “firebrands” like Hugo Chavez (now his legacy), his nationalism, his socialism, his appeal to the masses and how that’s not going so well - same as in Cuba and Zimbabwe. But it went VERY well for the leadership and their relatives and their cronies, VERY VERY well indeed.
Trump is most decidedly not a socialist. Chavez was foremost a socialist, who used some populist rhetoric to appeal to the masses. To compare these dictators to Trump is patently ridiculous and only goes to show you are detached from reality when it comes to Trump.
The way I see it, populism has always dominated in the South and often in rural areas elsewhere in the country. Over the course of the 1960s-1980s, these populists predominantly gravitated away from the Dems to the Repubs. It was only inevitable that eventually they would lead an internal revolution against the big international business, neo-con, globalist, elitist, open-borders Republican establishment because they outnumber the establishment. Buchanan tried in the 1990s, but the time wasn’t ripe yet. Trump has picked the right time when hatred of the establishment is at an all-time high, and he is now leading a revolution to shake up the antiquated and unrepresentative old party system—and it’s high time it happened.
