Good point from the CBC At Issue panel that while Pierre Poilievre and Jenny Byrne still seem to be content working to remove "not real Conservatives" from the party, Mark Carney is trying to include anyone he can, at least to a certain point. So Poilievre is trying to remove people from his big tent while Carney is trying to add people to his big tent.
There's a lot of Red Tories in the Maritimes, and urban centres, specifically the 905, Winnipeg, Edmonton, and Lower Mainland BC who would never see themselves as a part of Justin Trudeau's Liberals, but now see that they could be a part of Mark Careny's Liberals, and they feel alienated by the Conservative leaders and their ideological purity tests. A prime example is Doug Ford, who basically decided to be best buds with Carney and told Poilievre to FO. Now, you can debate all that and how allying with Doug Ford is questionable at best, but the realpolitik here is the Liberals would love the opposition to force an election because they think they would win, with ease, and Doug Ford would not explicitly endorse Carney, but he also would not endorse Poilievre. He would simply say nothing.
To summarise, what's going on is an internal battle unfolding for the soul of the Conservative party. Do they go full Trump, or do they go back to the Joe Clark/Brian Mulroney Progressive Conservative era.
In any case, for the immediate future the NDP are the lynch pin here, as they have no leader and really really do not want an election now. I suspect they all get sick or stuck in an elevator on the day of third reading of budget vote, even though they are on record they would not "vote in favour" of the budget, they way out is they don't show up so they don't vote against it.
Also there's Elizabeth May, but everything I've read is essentially everyone in federal politics is simply done with her, and they won't spend any time caring about what she has to say. That party she built had a great opportunity to advance around eight years ago and then they self-destructed because of her and their voter base requiring their own ideological purity.
