Hey Eagle, IMO Libs could leave it quite late to the point that even the most righ wing Abbott supporters accept they can't win with Abbott (thou that may need realy bad polls if the current ones are not bad enough) bring Turnbull in and a instant 22P would result with a very real prospect of election victory.
It may take more bad polls to make it obvious but IMO a leadership change in the Lib's is very much on the cards
