Incumbent Blake Moore (R) defeated Karianne Lisonbee (R) in the Republican primary for Utah's 2nd Congressional District on June 23, 2026.
The election took place in the context of redistricting, which changed the district boundaries from those used in 2024. Incumbent Celeste Maloy (R) ran for re-election in the 3rd District. Moore was the incumbent in the 1st District, which Utah News Dispatch's Alixel Cabrera said "[is] on a likely path to turn blue ... It’s a major shakeup for Republicans, who have occupied all federal offices in recent years." Utah Senate President Stuart Adams (R) endorsed Moore and Utah House Speaker Mike Schultz (R) endorsed Lisonbee.
The redistricting occurred in November 2025 after a state judge ruled the legislature had violated voters' constitutional rights when it overturned Proposition 4, a ballot measure voters approved 50.3%–49.7% in 2018 that created an independent redistricting commission. Politico's Samuel Benson said Moore's co-chairmanship of the committee that supported Proposition 4 "is fueling a primary challenge and could potentially hinder his future hopes at statewide office ... Lisonbee and other political foes have nicknamed Moore 'Salt Lake Blake,' suggesting he run in the blue district they blame him for creating." Lisonbee defeated Moore 61.5%–33.7% at the nominating convention. Utah Political Watch's Bryan Schott said, "Moore has never won the delegate vote at the GOP convention."
