Personally I'll vote for whichever/whoever stands up and says "Sorry I f*cked that up so I've changed my mind and am prepared to admit it" Honesty is what I'm looking for. Never find it of course. 
I certainly wouldn?t hold your breath while waiting!
Perhaps Cameron has a plan to bring his leadership to the edge of a precipice and then say ?one has fucked-up??
Nah?
