I'm sure there are. I'll give an example. When it comes to Finance, I'm sure Scott Bessent is much more intelligent than I am, but he is still a Trump boot-licker. Many Billionaires are also smarter than I am because they found a way to buy a Presidency.
Yes.
I think if you take away the plutocrats and racists (which form the major coalition groups of the GOP today), there would not be much polarization or political difference. They know their positions hurt people. It's just that they believe that if they have a government that doesn't help anyone (er, "freedom"), then people in positions of vulnerability in society such as the poor or racial/religious minorities will get hurt more than everyone else. And that makes it worth it for them.
Just ask their political strategists (interview with Lee Atwater, chief campaign advisor to Ronald Reagan and senior Republican Party strategist, in 1981):
"As to the whole Southern strategy that Harry Dent and others put together in 1968, opposition to the Voting Rights Act would have been a central part of keeping the South. Now [Reagan] doesn't have to do that. All you have to do to keep the South is for Reagan to run in place on the issues he's campaigned on since 1964 [...] and that's fiscal conservatism, balancing the budget, cut taxes, you know, the whole cluster…
You start out in 1954 by saying, "Nigger, nigger, nigger." By 1968 you can't say "nigger"—that hurts you. Backfires. So you say stuff like forced busing, states' rights and all that stuff.
You're getting so abstract now [that] you're talking about cutting taxes, and all these things you're talking about are totally economic things and a byproduct of them is [that] blacks get hurt worse than whites. And subconsciously maybe that is part of it. I'm not saying that. But I'm saying that if it is getting that abstract, and that coded, that we are doing away with the racial problem one way or the other. You follow me—because obviously sitting around saying, "We want to cut this," is much more abstract than even the busing thing, and a hell of a lot more abstract than "Nigger, nigger."
