Since I'm probably getting some downvotes that belong to Trump, I think the dude stands for nothing in particular; he's been boring me since the 80s when I first heard the name, and he's pretty much the last thing I'm interested in talking about.

Looks like I got the literal translation of "reductio ad something" right though. Also seems like the spirit is the same between me and Leo Strauss about how said reduction results in something pat, neat, simple and intellectually lazy. That's what I experience every time someone tries to tie up something interesting & complex with a nice Trump ribbon. It has been "reduced to Trump."
