CHEYENNE, Wyo.- Saying it’s time for a new generation of leaders in Washington, Liz Cheney, the daughter of former Vice President Dick Cheney, announced Tuesday she will run against Wyoming’s senior U.S. senator in next year’s Republican primary.

Cheney is taking on popular Sen. Mike Enzi, who announced almost simultaneously on Tuesday his plans to seek a fourth term.

Cheney’s announcement is a political challenge unlike anything Wyoming has seen for years, maybe decades.

Liz Cheney, 46, is the elder of the two Cheney daughters. Married with five children, she was a resident of Virginia until recently. She and her husband bought a home last year in the posh northwest Wyoming community of Jackson Hole.
