I'm almost afraid to help take their side, because I agree that the NDP did this to themselves with the infighting. Now before you go telling me that my brain is mush, let me try and explain why people voted ABC this last election.
They held on to Singh too long, he wasn't drawing people in to the party. Say what you will but Polievres attacks at him driving a Maserati was successful at having people I know that support NDP questioning why a rich lawyer was running the party.
There are also the other end of the NDP fan spectrum that I know from my time in construction, the types that used to see them as the labour party. They have absolutely lost that title on Ontario to the Conservative party, and have instead been positioned as the "human rights" party. Everyone who used to support the NDP on that front got tired of hearing about Gaza over the election cycle, and didn't feel the NDP should be as vocal about that as they were.
Then there was the TFW/immigration support they went heavy on during the election, when all polling was showing the unpopularity of those systems, and wanting the numbers to be lessened. The NDP used to be against the TFW program, and it was positioned very successfully that they were supporting of it this last election.
You talk about how they formed the coalition to get things to work, I agree, that was the right move to get Pharmacare. But all that did was position the Liberals as a party willing to make those changes, and in the past election cycle, there was little chance voters would give up a party willing to do that for the Conservatives.
Now the fear should be who will lead them next. I watched the NDP leadership debate last night. There aren't really any people running that have charisma and the ability to get people behind their cause. I think we'll see the NDP suffer for another election cycle or two federally.
