Bannon is an idiot. Trump is a greater idiot. People who were easily manipulated in exactly the same way using precisely the same playbook as in the 1920s and 30s (and, indeed, as in every prior century) voted for idiots at the behest of idiots because they’re idiots. No power (or Power) involved, and no voices either, just confirmation bias and assholes willing to leverage it to get into office.
