WASHINGTON — Liz Cheney intends to withdraw from the Wyoming Republican Senate primary, according to two sources familiar with her plans, bringing an abrupt end to her unsteady challenge to the incumbent, Michael B. Enzi.
Ms. Cheney, 47, the former vice president’s elder daughter, is expected to drop out of the race this week, citing family reasons. She did not respond to emails and phone calls late Sunday.
Since declaring her candidacy in July against Mr. Enzi, a well-liked, three-term Senate veteran, Ms. Cheney not only never found traction but also wound up causing deep rifts among longtime friends and even within her own family.
Her task was always going to be difficult. Unlike some of the other sitting Republican senators who have been challenged in primaries in recent years, Mr. Enzi has a solidly conservative voting record and did not present the sort of vulnerabilities Ms. Cheney could exploit. But Ms. Cheney never was able to focus much on her opponent, spending much of her five-month candidacy fending off distractions to her campaign.
