Remember when the Liberals, NDP, and the Bloc Quebecois offered an idea in coalition against Harper during the recession of 2008. The Liberals were the ones to back out.
If the Conservative Party keeps being antoganistic, partisan, tone deaf..... I would not be surprised entirely if this crisis continues Trudeau himself might actually look for a stable government somehow. It would be the responsible choice in some way. Unlike then, we need a coherent government leading, which I do actually feel he is leading in context. Not many leaders have faced this kind of crisis, a meltdown of the financial structure of our society is different than our collective health creating that downfall.
I'm sure, the NDP, the Bloc actually showing many shared values could stop an impasse that Scheer wants to create, even though he is on his way out. If the Conservative Party had smarts they would dismiss him and appoint an interim leader until they can select another leader... Alas, the tone deaf one wants MPs travelling, subjecting people 'hey you can sit beside my family; I trust them'. (paraphrase of what happened) That's not how viruses work. They are a little more relentless.
Now might be the time to float the idea of a government in accord; which I feel would hold the Liberals more accountable than political grandstanding by an outgoing leader who didn't complete his college program in accounting.. It's attention seeking; obvious and callous.
