Interesting, in my bubble “populist” right refers more younger more paleo conservative types who feel betrayed by MAGA. Many of these people hate Thiel and Technocrats as much as my Marxist friends.
I’m gonna guess (and tell me if I’m wrong) the disconnect is that you may be referring to the Trump admin itself which is indeed in bed with Thiel types. Personally I don’t really bother considering them populist anymore. They seem to mostly be interested in enriching their little circle.
