I wouldn't write the BC Liberals obituary yet.  True they struggled in the Lower Mainland but in Greater Vancouver as a whole the popular vote was 41.1% to the NDP's 43% and they won 17 seats vs. NDP's 25 seats so wouldn't take a huge swing to flip it back in their favour.  At the same time if they do somehow form government I cannot see them doing better next time, but if they spend a few years in opposition there is no reason they cannot regain some of those seats.  Unlike the Ontario PCs or federal Conservatives, the BC Liberals are quite flexible in ideology so they don't face quite the same obstacles those two do.
