Make no mistake - of those 8% at least half are protest voters who will vote for whatever new party they see as anti-establishment. The pirates will lose those when they first become part of a government and have to do compromises, or when a newer anti-establishment party appears, whichever happens first. The pirates may still grow a little, but then they will see a sharp drop in votes, unless they can achieve some truly spectacular successes. How the deal with that drop will determine whether they have long term viability.
