Another factor to be taken into account:  BC has a long tradition of MLAs crossing the floor.  W.A.C. Bennett himself was one such.  His son Bill's cabinets were full of rebranded Liberals, including the execrable Bill Vander Zalm. 

The current BC Liberals (actually Socreds in Liberal clothing) will now go for new leadership.  That will create winners and losers, and the losers may be susceptible to temptation:  i.e., join us and be a cabinet minister.

It will get very interesting.
