I think the NDP organizing and devoting 4 or 5 or whatever months to getting feedback on policy from EDAs is a good thing. It was a pretty detailed and extensive process. I'm certainly not aware of other mainstream parties like the Libs or Cons ever doing something similar.
If the NDP hierarchy were actually interested in getting feedback from members regarding the Leap Manifesto, they would have ensured that meetings to discuss it would be held in each riding, and that the results of these meetings would be included in the report on the matter.
In any ridings in which such a meeting was not held -- and I'll venture an educated guess that this includes most ridings -- NDP members were not provided the opportunity to give their feedback on the Leap Manifesto.
