I don't believe this at all - the GOP is getting more and more diverse and there is no explicitly racist GOP policy. This is untrue for European ethno-nationalist parties. Sure there maybe a couple of closet ethno nationalist in the GOP but they would be thrown out if they said the stuff their Euro counterparts say in the open. There's also the fundamental reality that because of the 2 party system and the demographics of this country that the GOP could never become an ethnonationalist party. Maybe unless PoC become white supremacists themselves like the Chapelle show skit :D.
