There's a reality in the fact that the goals have been the same since 1968 (and before), but the tactics have evolved/changed. The mainstream of the Republican Party was not willing to be openly antagonistic to democracy, as a concept, in the way they are now. That's pretty significant.
Do you not think the end of Jim Crow wound have changed the goals, in order to allow them to return to Jim Crow era goals, and that time, context and conditions would enforce an evolution in tactics or do you think we should all pick up some muskets and head to a nearby hand operated printing press?
