Rep. Kevin McCarthy’s ascent to speaker of the House is no longer the cinch that it was supposed to be just one week ago. His admission that the Select Committee on Benghazi has been a successful political enterprise against Hillary Clinton was viewed as an amateurish red flag. He remains the favorite, but his display of public-relations weakness has at least opened the door for a relatively legitimate challenger. Jason Chaffetz, a Utah representative elected in 2008 who chairs the House Oversight and Government Reform Committee, formally announced his bid to replace Speaker John Boehner on Sunday.
