Evola deeply valued inner strength, personal autonomy, sobriety and anti-materialism. I believe that he would support whoever can live up to those ideals. It is very difficult for me to think of practical examples, since he has criticised many things and every political subculture I know of today subscribes to at least one element he would object to.

Also are there any white nationalist writers and speakers in the last 70 years or so that most closely mimics Evola's ideas? Bowden? Pierce? Duke? Metzger? Yockey? I don't know much about Evola so I'm trying to figure out how he fits into modern white nationalist belief structure (if there even is a consistent modern white nationalist belief).

I can't think of anyone that holds the same ideas. From the ones you named, I think Bowden and Yockey probably come closest. Bowden had actually drawn on Evola's work and even given lectures on Evola, but to my knowledge he was most interested in the Nietzschean element. I have not read Yockey's Imperium, but as far as I am aware, Evola had a mixed opinion on it. Yockey's views are centred in the ideas of culture, civilisation and ontology, so he comes a lot closer to Evola's anti-materialism than most, but he still does not affirm Evola's transcendent values.
