They ride the "we are new" horse themselves, to explain their lack of expertise and knowledge in many pressing political issues. They are a new party, so people will look over some gaps, but this cannot last forever (maybe not even until the federal election next year).
Indeed. I also expect they will have the usual turbulence of a new political movement. Infighting, policy changes, etc and that all of that will be used to again dismiss the larger reason for their existence.
