**Incumbent Lauren Boebert advanced unopposed through the June 30 Republican primary in Colorado’s 4th District and remains the party’s nominee for the November 3 general election.** The solidly Republican district, where the seat has been rated Safe or Likely Republican by multiple forecasters, shows no signs of an intra-party challenge or withdrawal pressure despite a May dispute with President Trump over her defense of Rep. Thomas Massie and a September ethics complaint alleging improper staff relationships, which Boebert’s office called “utterly false” and politically motivated. Fundraising data through mid-2026 indicates limited cash reserves but highlights comfort with the district’s structural advantages. Recent personal developments, including her son’s sentencing, have not altered public campaign activity or prompted any statements about stepping aside. Traders therefore assign an implied 91.5% probability that she will stay in the race through Election Day.
