CNN Breaking News Email:

"First on CNN: Liz Cheney, whose bid to unseat Wyoming Sen. Mike Enzi sparked a round of warfare in the Republican Party and even within her own family, is dropping out of the Senate primary, sources told CNN's John King.

Cheney, the eldest daughter of former Vice President Dick Cheney, began telling associates of her decision over the weekend and could make an announcement about the race as early as Monday."

Hope this means we hear and see less of Darth Vader.
