Far-right congressman who became unlikely GOP critic calls it quits

Rep. Ken Buck said Wednesday that he wouldn't run for a sixth term, an unsurprising decision that followed Buck's surprising emergence as an outspoken critic of his own party.

The Colorado Republican told MSNBC that his decision stemmed from his disappointment "that the Republican Party continues to rely on this lie that the 2020 election was stolen and rely on the Jan. 6 narrative and political prisoners from Jan. 6 and other things." Buck nonetheless voted to make election denier Mike Johnson House speaker last week, explaining his choice by saying, "I think people make mistakes and still could be really good speakers."

Buck, who remains a member of the Freedom Caucus, was a hard-right ally during most of his time in national politics, and hardcore conservatives are in a strong position to retain his seat. The 4th District, which includes dark-red eastern Colorado and GOP-leaning suburbs of Denver in Douglas County, supported Donald Trump 58-39.
