I think they're generally just capable enough to not casually make enemies of each other, as they're both very influential people. They do speak the language of power and money.
But also they are both egomaniacs that choose strange hills to die on. So I could see an ill-advised falling-out.
Side note, I hate that as a society we're forced to waste any degree of attention on these thoroughly awful people.
I dislike this saying because it's always been assumed, never proven, that intelligence follows a normal distribution. That is if it can even be mapped to a single, consistent, comparable number.
But your point is valid. Though I'd add that it's not universally true. Fascists thrive on fear and ignorance. Give people access to a good education, which includes political education, and they are far more resilient to these tactics.
Which is why it's especially nefarious that conservatives love to undermine, vilify, and defund education.
