-Came to power at 40. People know he could have 50 years to reward/protect them for doing bad things for him, and the same in which to take revenge on them. -Only a democracy since 1989, meaning people remember dictatorship (some fondly.) -World media doesn't give a shit what happens in Hungary.
-Hungary is hugely white/Christian. Immigrants there are often brown, Muslim, and poor, and don't speak Hungarian = easily othered. Trump is up against a proud "melting pot" tradition, with immigrants who speak English/Spanish, start businesses, and are largely Catholic. Most people like 'em.
