Citing “serious health issues” in her family, Liz Cheney has dropped her primary challenge against Wyoming Republican Sen. Mike Enzi, ending a bitter political contest that had spilled over into a public fight over gay marriage with her sister.

In an official statement released by her campaign,the eldest daughter of former Vice President Dick Cheney said the health of her family was her “overriding priority.”

“Serious health issues have recently arisen in our family, and under the circumstances, I have decided to discontinue my campaign,” the statement said.

“My children and their futures were the motivation for our campaign and their health and well being will always be my overriding priority. Phil and I want to thank the thousands of people in Wyoming and all across the country who have supported my campaign.

Her Wyoming credentials were challenged in spite of her family’s deep roots in the state, because she spent much of her youth and adult life in Virginia.

Last summer, she committed an embarrassing political gaffe in a state where hunting and fishing are taken very seriously by mistakenly buying the wrong fishing license after living in Wyoming for just a few months.

Then a bitter spat over same-sex marriage between the Cheney sisters spilled over into the public arena when Mary Cheney and her wife, Heather Poe, took to social media to blast the elder sister for her continued opposition to gay marriage.
