Yes it really is as simple as what you just said. I find it funny and sad when opponents of Trump do all these weird mental contortions to explain why he won, from “trump voters are brainwashed rednecks” to Russiagate. Turns out some people do want lesser taxes, lesser regulation, don’t care for abortion and simply don’t mind trumps buffoonery. And no, not all of trump voters are racist. I might even say a negligible fraction are actually racist.
