Paraphrasing from OPPO: "The Greens should stop running as (centrist) German Greens and start running as (leftist) Nordic Greens. If they do that, there is a lot of room for growth and they could eat the NDP for lunch."
Yes! This!
Replacing Elizabeth May (who I mostly like) couldn't hurt. Although she is generally a good parliamentarian, she is kinda dull and lacking in charisma. Someone more dynamic could attract new voters (keep May as an important advisor to said person).
