It's a decently effective strategy. Essentially these MPs have to shut up until Canadian voters hand them the keys, then they can do whatever they want because they promised very little.
While they stay meek, oil money is being flooded in hyping up Poilievre and the conservatives in extremely generic terms. I'm no strategist so I have no idea how you counteract that.
Trudeau and Singh need to work something out very, very soon, because 24% + 18% of the vote = 24% of the seats in FPTP math.
My thoughts are we need someone like Notley or Beck, a highly respected Prairies NDP member, who are progressive but also in touch with issues that matter with rural people.
