Where does the assumption that the average Liberal or NDP voter support Trudeau/Singh?

I'd say I align closest to a Blue Liberal/Red Tory. I, and most people I know who are Liberal supporter but not party members, think Trudeau isn't a strong leader, and if his last name was Smith may not even be in cabinet.

I'd bet most traditional Liberal voters want to see a leadership change.

However, if the choice is between Trudeau and someone hobnobbing with white supremacists, wants to take away healthcare for women, and eliminate rights for the LGBTQ2S+ community, then even if they don't like Trudeau, they'd still vote for him.

The real problem with federal politics in Canada is that to be elected party leader is a completely different criteria than to be elected Prime Minister. The CPC won't vote for a centrist from the East (Pollievre is Ottawa based but from Calgary); Canada as a whole won't vote for a far-right populist from the West.

I'd love a fresh new leader to come in, for each of the parties. The big issue, as others have mentioned is... who wants the job? I sure as hell don't.
