I'm not sure that is a fair characterization of his preferences. This is a guy who just wrote a book called "One Billion Americans" which argues that we should quadruple the US population through both pro-natalist policies and more immigration. I wouldn't really consider that a "moderate" position.

His other shtick though is "popularism" which is just that politicians should focusing on doing things that are broadly popular. It is (on my reading at least) not so much that this is "desirable" in a normative sense, but just that it is the only way to actually make progress.
