WASHINGTON — Rep. Lauren Boebert’s grip on Colorado’s 3rd Congressional District didn’t seem in question heading into last year’s midterms. But in the end, the congresswoman who gained a national reputation as a combative member of the “Make America Great Again” movement won reelection by just 564 votes. “This was supposed to be a slam dunk for the Republican candidate, the way the district is designed,” said Don Coram, a former state senator who unsuccessfully challenged Boebert in the GOP primary last June. Boebert’s near miss was emblematic of the difficulties Republicans confronted in 2022 and may face again in 2024.
