What Did You Know and When Did You Know It: "Characters" in "All the President's Men"

Watergate remains the gold standard of American political scandals, the reason every incident that might embarrass a President inspires a "gate" - "Contragate," "Monicagate," "Benghazigate," ad nauseum. And we might never have known about it if it weren't for the doggedness of Washington Post reporters Bob Woodward and Carl Bernstein and their editor, Ben Bradlee (RIP). The whole warped, pathetic, hilarious saga is detailed in the Woodward and Bernstein book "All the President's Men," which features a "cast of characters" in the preface that remains a good historical guide to the main players in the greatest Constitutional crisis of the 20th Century. Who do you remember?
