If Democrats in the 1960s had embarked on a multi-decade master plan to remove and replace capable Republican office-holders and officials with morally questionable, semi-competent characters who knew how to say things the base wanted to hear but never took any real action to roll back the collectivist agenda, the final fruition of that plan would look a lot like the political landscape today.

Just sayin'...

They did not have to "remove" many federal executives who were Republicans.

By the 1970s, it was impossible to get promoted in the federal bureaucracy (and many state bureaucracies) if you were not a card carrying Leftist.
