You can paint a similar history of the welfare state, which was first secured by assuring racist white Democrats that the pariah of black America would be cut out of it. When such machinations became untenable, the strategy became to claim the welfare state mainly benefited blacks. And as that has become untenable, the strategy has become to target the welfare state itself, with no obvious mention of color. At each interval the ostensible pariah grows, until one in two Americans are members of the pariah class.
In all this you can see the insidious and lovely foresight of integration which, at its root, posits an end to whiteness as any kind of organizing political force. I would not say we are there. But when the party of white populism finds itself writing off half the country, we are really close.
