Here is another article from rabble with some suggestions that would be great for the NDP and terrible for the GPC.  Duncan Cameron states the following in the article:

Working outside Parliament the Green Party is not going to set the agenda for public policy. In elections to come it will continue to be a spoiler, serving to enhance the chances of electing MP's hostile to its cause.

If the NDP lived up to its commitment to push for electoral reform then it would not be necessary for the Greens to work outside of Parliament.  In many countries Greens have started achieving many of their goals with the level of support equivalent to the GPC in Canada.  It is the first-past-the-post system that is the problem, not the strategy of the GPC to run candidates.  With proportional representation the GPC would already have 13 or 14 MPs (4.5% x 308 ridings). 

As I outline in this essay I think we will be able to win Parliament in the long term and I suspect supporters of other parties are starting to wake up to that fact.  It isn't a surprise to me that we are hearing suggestions from NDP supporters that we should merge, not run candidates, etc.

However, there is a role for the Green Party. Should Elizabeth May take on a unite-the-left strategy, by creating a Green Democratic coalition with Jack Layton, then we could see a Green agenda in Parliament that would lead rather than lag behind public opinion on issues such as climate change.

As I outline here the GPC does not draw it's votes exclusively or even primarily from left-leaning voters, which means it is not a party of the left.  A unite-the-left strategy should take that into account!  Green Party supporters are not wayward NDP voters and we have an important and unique voice to offer Canadian politics.  It would be beneficial for Canadians if the NDP and other parties started working for the electoral reform that was proposed to Parliament by the Law Commission of Canada years ago and is now long overdue (more in my next post).
