I think she knows she's done. She won't win the 4th district seat because more popular republicans will win the primary and then the seat. She could beat her primary challenger in the 3rd district, but then could lose to Frisch. This way by moving districts it will be Jeffrey Hurd Vs Adam Frisch and then Frisch is more likely to lose and a republican wins.
She won't win Buck's seat. But her switching districts reduces Frisch's chance to win the seat. Which is the whole point here. This is Boebert's way of stepping down, while saving face and making it look like she never gave up.
