Citing "serious" family health concerns, Liz Cheney, daughter of former Vice President Dick Cheney, has ended her Republican primary campaign challenge in Wyoming against the incumbent, Senator Mike Enzi.
Cheney's surprising decision to jump into the race, an announcement made in a YouTube video last summer, roiled Republican politics in the Wyoming, a state that Dick Cheney represented in Congress for five terms before moving up the Republican food chain in Washington.
Enzi was a low-key presence in Washington who was elected in 1996 and, with few blemishes, amassed a conservative voting record in the Senate. He expressed public annoyance at Cheney's decision to mount a primary challenge. A number of his Senate colleagues quickly rallied to his side and pledged support for his re-election bid.
