I think it would take another Elisabeth Freeman and W. E. B. Du Bois, I am referring to their work of showing the horror and unethnicality of the lynching of Jesse Washington.
The Republican voters are not looking for good governance at all, they would fully support an autocratic oligarchy like in Russia, as long as they could keep hating the browns, the blacks, the gays and oppress women's rights. Give them that and they will give you all the power.
It's just an expansion of this quote from Lyndon Johnson below. One of the greatest quotes by an American president ever. It's not just the blacks anymore though, but the thought is still there
""If you can convince the lowest white man he's better than the best colored man, he won't notice you're picking his pocket. Hell, give him somebody to look down on, and he'll empty his pockets for you."
