If my domestic / relationship situation was different, I'd work for / with Dominic Cummings[1].
He's not the devil, and I don't know David Berman so will not compare, so I'm sidestepping your OP question.
I'm also not a fan of the in-power Conservative party (his previous employer) we have in the UK right now, but there's something about him and his tactics that give me a gut feeling it'd be the wildest of wild rides, and there's something perversely appealing about that to me.
This probably says more about me and my chosen career path to date than anything else.
