Stupid, stupid move by the Conservatives -- A-1 dumbfuckery.
Although I have not voted Conservative since the days they were the Progressive Conservatives, I will say that O'Toole was the only visible hope of getting the CPC to go back to being the Progressive Conservatives, which is where they need to be.
O'Toole didn't lose the CPC the last election, the CPC lost because the party is steeped in angry US Republican types (think MP Candace Bergen wearing a MAGA hat) whose views do not match those of Canadians at large.
The CPC scrapped Canadian-style conservatism for US-style Republicanism -- which is never going to fly Canada-wide -- during the Harper years. The CPC desperately needs Ontario and urban Canadian votes in order to win elections. As long as they are taking the social conservative path, they do not stand a snowball's chance in hell of achieving that.
The CPC is little more than a regional grievance party for Alberta and Saskatchewan these days. That's it. There is so much infighting within the party that if five CPC MPs stand up to support a policy, five more will become enraged.
Denying climate change, denying science in general, being in favour of loose gun laws and having a party full of religious whackjobs is never, ever, ever going to fly with Canadians at large.
Good luck to the Conservatives; they're sure as hell going to need it.
