They also want RedNexit bad, despite how impractical, unrealistic, shortsighted, and outright asinine an idea it is. So, I'd say let them have their delusions; they're still a small, albeit obnoxious, minority from a national perspective.

And the popular vote is wholly irrelevant in Canada's electoral system. But FWIW, the LPC won more seats in 2021 than 2019; the CPC neither gained nor lost any. What isn't mentioned but should be stated for its significance is the NDP swing increased, as well as that of PPC, the latter of which doesn't bode well for moderate conservatives. 2019 was a far more successful result for the CPC and they've only become even more fractured during O'Toole's tenure.
