Lyndon B. Johnson

Johnson enters as the overlooked vice president standing in Kennedy's shadow, a big, blunt Texan used to being underestimated by the Washington glamour around him. Thrust into the presidency by tragedy, he moves quickly and plainly, more interested in getting things done than in being liked or admired.

Clancy Brown brings his imposing physical presence and gravel voice to a man written as pragmatic rather than poetic, a deliberate contrast to Kennedy's polish. The show uses him to explore how power actually changes hands, and Brown plays that transition with unshowy authority, never straining for sympathy or grandeur.
