How many pre-1964 southern racist Democrat bigots did NOT join the Republican party after 1964?

Are these types of questions seriously trying to postulate that the current Dem party is "more racist" than the current Republican party? No matter what kind of tortured, simplified, historical lecture you try to give, the Democrats are currently the party that represents most people who are not white. So it doesn't matter what you say, all you have to know is that.
