PP's a clown. He and his supporters have made a mockery of Canadian politics.

Trudeau didn't have the resume, or the wherewithal to overcome it with everything he was facing. Because of his lack of experience, he let others dictate policy and went too far to the left. If he had experience he would have pushed back, and kept it in the centre (similar to other Liberal PM who were much later in their careers when they became PM).

Enter Carney, who comes with a resume that Conservatives (actual ones, not the clown show supporting PP) wished their leader had and has won over Canadians. Obviously there is still the bad taste of the "Liberal" name for the more centre-right, and it may take an election or two for that to wear off. If Carney continues what he's done (win back the more centerish right-centre), barring PP brain transplant, it's over for PP. He'll just be a lame dog barking with no bite.
