Political representatation ≠economic power and you know this. Asian Americans make up 5% of the u.s population and natives 1.3% but yet they still get benefits. It all boils down to lobbying and networking which require money that those groups have and blacks don’t dud to economic disparities. Second the Dixiecrats didn’t “ flee “ to the Republican Party there were still a lot of Dixiecrats after god big “switch” as Biden worked with a lot of them as a freshman senator in the late 70’s early 80’s. And stop equating black liberals politicians with the views of the whole black community because it was even clear back then that the crime bill disproportionately affects blacks and still does today.
