Well perhaps sick of ElDorito and the parasites like him. Exceptionalism was based on the notion that the US was in a new channel uniquely different from empires of the past. "A Republic if you can keep it" as a founder said knowing full well how Rome degenerated into autocracy in the first century. A competent Trump is coming so the not an exception after all. Few Amercians will even know Rome was a Republic for 450 years before the first emperor came to power. Fewer will understand how they abhorred kings but as a militarised society perceiving threat were foxed into accepting a "commander", not a king, which is what emperor means; imperator in Latin.
