>>485578I would be cautious about taking the electoral result as an objective barometer for the level of support the greens have. It's somewhat likely that it does not reflect reality.
If you are being realistic the goal of a third party has to be about creating and growing organizations, networks that link people together, that enable them to act as coherent groups rather than disorganized individuals. You know informal political power.
If you have gained sufficient informal power, the official system will be forced to let you have formal political representation.
The electoral system by it self looks rather closed off, it's unlikely that a new party could rise up inside that system. So look at the electoral system as a place to advertise and recruit, more than anything.
