Depends what happens.  If the BC Liberals are propped up by the Greens, yes the desire for change will be even stronger and so they will probably lose although unless another party on the right or in the centre emerges they will still be competitive.  If however the Greens and NDP oust them then it will depend on how they perform.  If they perform badly, the BC Liberals could easily make a strong comeback, much like the Social Credit did in 1975 when they ousted the Barrett government or even the NDP under Carole James in 2005 who despite not winning got a higher share of the popular vote than either Glen Clark in 1996 or Harcourt in 1991 and finished only four points behind after a massive defeat four years earlier.
