Truth be told Drumpf coalition would probably be quite salient it if wasn't for his sleaze and Russiagate. We see that increasingly in Europe. It's a question of the messenger, not the message.
I will also add they will eventually have no choice but to counter Democrats over-the-top female identity politics by playing over-the-top male identity politics. It's the only way they will start peeling off a good chunk of non-whites votes.
It wouldn't work, because for Republicans their over the top identity politics is all about defending entrenched interests, and most minority males won't sympathize with that.
