The Liberal Party in Canada has no way to profit from aligning themselves with a 100 year old nazi. It's actually quite damaging to them, as you can see.
But it DOES have a VESTED political interest in aligning itself with Ukrainian nationalists in the diaspora here in Canada. THAT, has political value. Anticommunism in a country FULL of people whose family origin story in this country is "fled Stalin" has VALUE.
It's not that they love nazis; it's that they love votes, and hate commies, more.
