I disagree with the conclusion. I think it is the same base. Trump is just more outlandish and goonish because he is not that bright and a poor politician compared to his neo-fascist/neo-liberal predecessors. Trump is an outstanding self-marketer and just slightly less sucky of a politician than Hillary Clinton — which is how he got elected — but his numbers, even among the GOP, have fallen since his election. The GOP base was hoping, like those Trump né two-time Obama voters, that the Donald would actually “drain the swamp” and stop our senseless wars in the middle east.
I would like you to be right, but I think that’s somewhat wishful thinking. The Overton window among the right has been moved by decades of neoconservative oligarch and evangelical influence, and I think the messaging coming from these groups has shifted the Republican mindset more toward fascism. It’s not clear to me that a neofascist could have won a decade or so ago.
I don’t think it matters if any swamps are drained or walls are built as long as Trump keeps calling Black NFL players who take a knee “sons of bitches,” openly insults mainstream politicians on the right and left, refers to the “very good people” among white nationalists, attends homophobic Christian conferences hosted by hate groups, and so on. In the continued absence of any legitimate opposition from the left, he only has to keep pandering to this same degenerate base to retain approximately the same level of approval and influence as he had on Election Day. Even a large number of people who hate him still prefer him to the “greater evil” (from their perspective) of a mainstream, establishment corporatist.
