Incumbents face a tough 2026 primary landscape as generational shifts reshape Congress
Ten House incumbents have lost renomination in 2026—the most in non-redistricting years since 1970—split 7 Democrats and 3 Republicans. While mid-cycle redistricting contributed in some races, experts say a broader antiestablishment mood and generational/ideological shifts are driving challengers from the left and loyalties to party leaders are waning. Notable defeats include Democrats John Larson, Dan Goldman, Adriano Espaillat, Shri Thanedar, and Diana DeGette, and Republicans Thomas Massie and Dan Crenshaw.
