Green Party Strategy

It's fairly obvious that the Greens are not going to be a major force in this election. However it is entirely possible that they could hold some balance of power and be influential if they increase their vote. How do they do this?

The main mistake that Green parties across the world make is to focus on their "greenness" during an Elction campaign. You know what? We can tell by your name that you are environmenetally friendly. What we want to know is what you are going to do about crime and schools and the hospitals.

I disagree with the decision to preclude the Greens from the television debates but they need to promote thselves as more than a one issue party in a much more effective way.
