Either they agree with the mission or they are going against their principles for political gain. Which do you think it is Fidel?
The NDP wasn't doing much good for anybody when they were at 10% in FPTP opinion polls.
You are right but that still doesn't answer the question. If they look just like the other parties they may get the votes of the voters who used to vote for the other parties. It is a sound electoral strategy and should gain them power. Mulcair will follow in the footsteps of great NDP Premiers like Doer and Dosanjh.
