Republican Rep. Lauren Boebert, a renowned conservative firebrand whose combative style helped define the new right, is likely headed to an automatic recount in her bid to fend off a surprisingly difficult challenge by a Democratic businessman from the ritzy ski town of Aspen.

CBS News characterizes the race as "lean Republican," but on Friday, Boebert was leading Democrat Adam Frisch by just 551 votes, or 0.16 points, out of 326,965 votes counted.
