Nine of Idaho’s most conservative incumbent Republican legislators just got sent home — not by Democrats, but by members of their own party. In a stunning primary result that has shocked longtime observers of Idaho politics, moderate Republicans swept out nine far-right incumbents in a single night, fundamentally reshaping the balance of power in the state legislature.
The Fall of the ‘Gang of Eight’
The biggest story of election night was the near-complete collapse of Idaho’s notorious “Gang of Eight” — a bloc of hard-right legislators who had spent years blocking budget agreements, cutting education funding, and repeatedly pushing the state’s government to the brink of gridlock. By the end of the night, five of the eight members had been defeated. The Gang of Eight is now the Gang of Three.
Among those who won’t be returning to Boise: Senators Josh Kohl and Glenneda Zuiderveld of Twin Falls, and Representatives Lucas Cayler of Caldwell, David Leavitt of Twin Falls, and Faye Thompson of McCall. The Magic Valley region bore the brunt of the losses — three of the five defeated Gang members represented that area. Additional incumbents who lost included Rep. Mark Sauter, Rep. Tanya Burgoyne of eastern Idaho, and Sen. Jim Woodward, who fell to former state legislator Scott Herndon.
What Drove the Results
Moderate Republicans framed their victories as a long-overdue course correction — a message from the party’s own base that the chaos had gone too far. The Gang of Eight had become synonymous with legislative paralysis: failed budget negotiations, stalled education funding, and a governing style that prioritized ideological confrontation over results. Idaho voters, registered Republican and voting in a Republican primary, decided enough was enough.
Voter turnout for the May 19 primary came in at approximately 30%, a meaningful number for an off-year primary. Editorial writers in Idaho called the results a sign of “hope for better days ahead” — language that reflected just how deep the frustration had run. In a state where Republicans dominate general elections, the primary is where governing decisions are actually made, and this round of primaries sent a clear signal.
What Comes Next
The question now is whether this represents a durable shift or a single-cycle correction. Idaho’s far-right faction didn’t disappear — three Gang members survived. And the incoming freshman class will face the same pressures and ideological currents that produced the Gang in the first place. But for the first time in years, Idaho Republicans who want to govern rather than obstruct now hold a clearer path to doing so.
For Americans watching from outside the state, the Idaho results are a reminder that the most consequential political battles sometimes happen not in general elections, but in the primaries that most people don’t follow — where a party’s base defines what the party actually stands for.
