As I see it, I can choose whom to believe. I can believe that the BC Liberals will suddenly become less self-serving, less corrupt, and more democratic, or I can believe that the NDP will keep their promises. I have no way of knowing in either case, but the Liberals have been in power long enough that I can guessed based on their recent activity. If I'm unhappy with the NDP later, I don't have to vote for them again. Nothing done over a 4-year term is irreversible.
