281 | Trump Stress Test

David talks to the historian Sarah Churchwell about how well America's political institutions have withstood the stress of the last four years.  Have we seen the limits of presidential power or have we discovered how easy it is to trash those limits?  Are constitutional checks and balances still intact?  Is it really Mitch McConnell who is putting American democracy under stress?  Plus we talk about what will be needed to restore the social contract and the perils of political humility.
