I’ve never understood why black voters have voted so strongly Democrat in recent decades.
Somebody told me once that it was because of President Johnson and the civil rights laws of the 1960s. And LBJ was a Democrat.
Perhaps political rhetoric enters into it. We are told how Republicans are racist sexist etc. The implication then is that any blakcs must vote Democrat to keep racists out of elective office.
They started shifting with FDR.
