The BC Liberals are Liberals in name only and even less in common with the Liberals in Ottawa.  If the previous election wasn't able to provide any affects with the Liberal Party chanting "anyone but Christie", ( the now LIberal Premier of BC),  its highly unlikely it will cost Liberals any seats.  To enhance the view on this, consider the fact they won a majority after all that went on with CN Rail.
As for costing the Liberals seats in Alberta, I would have to ask ....what seats are you referring to since they have none to lose ?
