Europeans know how this goes. Viktor Orban, the rightist Hungarian prime minister, has established a template for the authoritarian system Trump would pursue if re-elected: neutralize an independent judiciary, demonize immigrants, claim the “people’s will” overrides constitutional checks and balances, curtail a free media, exalt a mythologized national heroism, and ultimately, like Orban or Vladimir Putin or Turkey’s Recep Tayyip Erdogan, secure a form of autocratic rule that retains a veneer of democracy while skewing the contest sufficiently to ensure it can yield only one result.
