The New Zealand Labour party has strangely appointed Matt McCarten as Chief of Staff. This is a bizarre move if they actually plan to win government - surely they would need to chase the center vote. This appears to be a move aimed at winning back the Green vote, maybe to shore up a shot at the 2017 election.
Chances are it may have the opposite effect, in that it drives the center left away.
Given Matt McCarten's outwardly hostile and offensive comments towards Jews and Israel, I can only hope that Labour never get close to power while he is around. While he is, the Green party are looking more centrist - especially when you consider he last came from Mana.
