Rep. Blake Moore, the House Republican leader in Utah, is facing a primary challenge from state lawmakers and party activists for his support of a redistricting commission. State Rep. Karianne Lisonbee has launched a campaign to blame Moore for the state’s map-drawing woes, which resulted in a new Democratic-majority Salt Lake seat, a seat previously held by Moore. Lisonbie has raised $150,000 and is campaigning to qualify for the primary ballot through Utah's unique party caucus convention system. Moore has received endorsements from U.S. House Speaker Mike Johnson, House Judiciary Chair Jim Jordan, and President Donald Trump, who endorsed Moore in November before a judge chose the new congressional map. The state Legislature is split over redistricting, with more than 30 other state lawmakers endorsing Lison Bee as a show of disapproval over the redistricting process.
