The revolt against a decision of the Coalition leadership by a group of Liberal and National Senators last night is just what's needed to kick along the leadership speculation. We can now expect Malcolm Turnbull to have plenty of silly season reading suggesting that his position in charge of the Liberals is in jeopardy.
The silent backbencher Peter Costello will be elevated by journalists into the position of the number one challenger whether he wants to be there or not seeing that Deputy Leader Julie Bishop's reputation is being tarnished every time she opens her mouth to speak.
Opposition Leader Turnbull should be hoping that unemployment starts rising quickly to take some of the gloss off Kevin Rudd. A series of bad opinion polls for him might even see the speculation of journalists come true!
