On this episode of The David Frum Show, The Atlantic’s David Frum discusses recent questions about President Donald Trump’s health and explores what a potential J. D. Vance presidency might mean for the country. He contrasts Trump’s impulsive, ego-driven style with Vance’s methodical, ideologically driven approach, examining how each wields power, pursues personal and political goals, and shapes domestic and foreign policy. Frum explains why understanding these differences is crucial for anticipating the challenges ahead.

Then Frum is joined by Jonathan Rauch, a senior fellow at the Brookings Institution and the author of The Constitution of Knowledge: A Defense of Truth. They discuss how societies decide what’s real, why disinformation has become a central political strategy, and living in a “reality-based community.” Rauch explains the dangers of the “fire hose of falsehood,” why authoritarian regimes weaponize confusion, and why, even amid today’s “machinery of lies,” reality still has the final word.
