Right now a third party is a wasted vote so we need more than 3 national parties in order for them to be viable alternatives to the current two. The Forward party and Green Party could cooperate in order to make this happen, but that’s probably just wishful thinking on my part.
I really can't see how multiple small parties teaming up helps anything. Maybe you can clarify? For as long as the big two are considered the big two, any number of additional parties act as spoilers.
