Well actually according to the rules it will. The reason the big 4 (CP,LIB, NDP, BQ) have refused to have the Greens in nationally televised debates was because in order to be in a debate they said you have to have representation in Parliament. If the guy becomes a Green, Ms. May will now be in the debates with Harper, Layton, Duceppe and whom ever the Liberals pick. There by getting the Greens message out to the public and forcing the other parties to become more pro environment for fear of losing power because as you said Power is everything to the political parties.
