As I recall Blacks were voting about 75%-25% against the GOP in the 1960’s.
My point was more along the line that a new and stunning level of undisguised Black anger and contempt for the GOP emerged around 1968.
Race was no longer the issue.
It was now an issue of deeply held political values.
I can agree with that, it became more of a thing of black against the system, against “whitey”, against even “Amerika”, a militant “black power” thing.
