How Parties Learn... if at all with Prof. Seth Masket | Political Reality | S01E08

Seth Masket explores the transformation of the Republican Party as conservative populist activists and Trump supporters eroded the influence of traditional party insiders. Drawing on interviews with local party officials and activists, the book traces the long-term changes—media ecosystems, grassroots movements, and strategic choices—that enabled this shift. Masket situates Trump’s ascendancy within earlier conservative movements and institutional weaknesses, showing how party authority can be undermined. He analyzes the implications for nomination processes, party endorsements, and governance when grassroots energy outweighs established party structures. The book provides a detailed account of party change and the consequences for American democracy.

Seth Masket examines the Democratic Party's internal debates and decision-making after the surprise 2016 loss, focusing on activists and early-state operatives who shape presidential nominations. He traces how competing explanations for defeat influenced strategy, candidate selection, and party priorities through the 2020 election. Using interviews and on-the-ground reporting, Masket reveals how narratives about identity, electability, and messaging competed within the party. The book highlights how parties construct lessons from single elections, sometimes leading to sincere reform and other times to misleading conclusions. It offers insights into the mechanics of party learning and the limits of translating electoral surprises into durable change.
