Jeff Crank won the GOP primary for Colorado's 5th Congressional District, defeating state GOP Chairman Dave Williams with 68% of the vote. Crank's victory represents a win for establishment Republicans over the firebrand faction aligned with Trump, drawing national attention and significant financial backing from conservative groups like Americans for Prosperity. Williams, who has faced controversy and calls for resignation due to his hardline stances and use of party resources for his campaign, received 32% of the vote. The race highlighted deep divisions within the Colorado Republican Party between traditional conservatives and the Trump-aligned MAGA wing. Crank's win positions him as the likely successor to retiring Rep. Doug Lamborn in this Republican stronghold. The contest attracted more than $2.4 million in outside spending, primarily in support of Crank.
