Wait, I'm conservative and my grandkids are half Mexican and my husband has black in his line. This is a lie spread by liberals. My grandmother hated blacks and was a Democrat. Blacks were forced into registering Democrat when giving the right to vote. When JFK, which had more of conservatism, tried to pass a civil rights bill got assassinated, Johnson wanted it pass to honor JFK. It wouldn't have passed if the Congress had been controlled by Republicans. It was a Republican controlled Congress that passed that bill!!!!
