Imma canadian. Can someone tell me why they switched???
My understanding is before the 60’s both parties just let the racist laws that segregated us go unchallenged because it was easy. As the 60’s went on and the civil rights battle grew they couldn’t ignore it anymore.
When Martin Luther King was arrested Kennedy called his wife to comfort her. He also started taking a stand on things like integration in the south. Johnson continued these policies and eventually signed the Civil Rights bill into law. As this happened the southern democrats (dixiecrats) who were about state’s rights (aka… “let us keep being segregationists”) left for the republican party.
