Matthew Dallek
Political historian; professor at George Washington University’s Graduate School of Political Management; author of Birchers: How the John Birch Society Radicalized the American Right (Basic Books, 2023). The wiki cites Dallek as the principal source for the revisionist account of the John Birch Society episode and the Buckley “purge” myth — see Debunking a Longstanding Myth About William F. Buckley (the Politico book excerpt that is currently the wiki’s primary engagement with his work).
Dallek’s earlier book The Right Moment: Ronald Reagan’s First Victory and the Decisive Turning Point in American Politics is also referenced in the wiki’s Ronald Reagan page for its account of Reagan’s pre-1965 ambivalence about the JBS.
Dallek is a historian, not a movement figure; his role here is methodological. His revisionism — drawing on Daniel Schlozman, Sam Rosenfeld, and his own archival work in NR correspondence — is a load-bearing input to the wiki’s Counterrevolution thesis. Stub for now; expand if more of his work is ingested.
