EZ, there's hope for Labour but they need to change their positioning if they want to govern again. I sense they are too 'mainstream' and not really that much different from National. They will only win in 2017 if the punters want new faces running he country, policies won't drive change.
Spain's a funny country. They had municipal and regional elections recently with some interesting results. Parties which had social or regional causes as their platforms did very well, based on high levels of community engagement and real passion. This no doubt will roll over to upcoming national elections.
As with Greece and to some extent the UK the political world is changing. Labour could become that champion of the people in NZ, but not where they are positioned now. Maybe to win they have to forget about left or right or centrist tags (whatever they mean) and become the party with compassion, organised compassion, and lead the conversation about how we can make NZ fairer and more equal for all.
Anyway EZ, have a read of this. I think there are messages somewhere in there for Labour
