You don't think Dems and GOP had a conference to agree to this, do you?

Of course not. It just happened. Because only one party can be racist at a time.

So before Nixon's Southern Strategy, the Dems were racist, after the Southern Strategy the GOP was racist. Nobody doubts this.

But it leads to some interesting conclusions, which I pointed out above.

Further anomalies are that George Wallace was both racist, and anti-racist, depending on the year. He was governor of Alabama until 1987.
