Nobody needs to adopt a PPC platform. They need to include those voters

It's the same thing. You "include" those voters by catering to their policy demands.

So you expect the CPC to shift far enough right to include the extreme right-wing fringes in order to recover that 2%.

Have you stopped to consider what the moderate swing voters (who BTW account for a hell of a lot more than 2% I might add) will do when the CPC goes full PPC? That's right, they swing to the Liberals. Why do you think the PPC are polling at 2% FFS?

You're basically demanding the CPC shift the whole blue area in this graph to the right: https://i.imgur.com/7zcsFr4.png

So does the CPC shifting right on that graph net a larger blue area or a smaller one? Obviously smaller because there's very few votes out at the fringes. Most votes are in the centre, and you want the CPC to alienate them in order to accommodate a tiny fringe of Qanon people and white nationalists. The CPC aren't going to do that. That would be suicide.

This is why I often suspect the PPC people on this board are Liberal astroturfers just trying to erode the CPC vote. Because your positions don't even make sense. You're going to punish the CPC by voting against them because they refused to take positions that would guarantee they lose in a landslide.
