They've been doing retrospectives on Watergate every week since it all started. Lefties in the establishment media keep wheeling it out and waving it around like a talisman. They are especially fond of remembering it when Democrat fortunes are down, like nowdays.
They do the same with JFK. They don't like to remember what JFK actually said or remember his platform because that contradicts their current one, (especially the one about not asking what your country can do for you) but they do like to remember the glory days of the Democrat party.
