The answer to how Trump has succeeded is really simple: He lies nonstop, and lying works. Sure, there are other factors in play—he tapped into and intensified a certain strain of profound proletarian resentment of liberal elites, and … well, that’s about it. But mostly, it’s the lies.
…And, to reiterate, Trump tells many such lies a day. He talks to the press two or three times a day most days, which probably adds up to what, 45 minutes, an hour? Spitballing it at one lie every two minutes, which may well be low, that’s around 25 factual lies a day.
I’d still rub it in on a tRump voter. They complain to me about losing Medicaid? I’d ask, “why are you so upset? This is what you voted for.”
