Well yes, depending on semantics it's a very different question, so that's kind of important.

And while certainly is an extremists, I don't think he his because of his fiscal policy or because he's rich. Except for him going crazy with the tariffs, it's mostly in line with what the republican party always did.

I'd say he's a political extremist when it comes to ignoring the law, immigration/deportation and the use of the ICE/military (both inside the country and against random boats now).

So yes, he is. But not because he's a billionaire (or rather millionaire).
