I'm just hoping in here (and will instantly hop out) to remind you guys that these Tories are not running in a primary that will immediately be followed by a general. Trudeau II can go until 2023, and that is a lot of time for things to change and polling numbers to go in any number of directions. Sure, Canadian minority govts are shorter, but the NDP would have to 'approve' the collapse of Trudeau II. This means that the NDP would need to see some reason to gain from a new election. So for better or worse, the next Tory probably has a lot of time ahead of him to lead the opposition.
After all, time will eventually rot everything.
Or Trudeau likes his poll numbers & - in the name of 'stability' or something like that - calls an election once we've generally returned to normal.
I thought the Comedy of Theresa May would have taught every anglosphere politician how horribly things like this can backfire in the modern era.
