What is your definition of 'win'? They're currently polling at around 20-25%. The traditional conservative party is polling at similar numbers and other parties have less. Obviously no party will take the majority of the vote. So what is your criteria for winning or losing? Even if the pirates election results were 5-10% less than the polling numbers they'd still have 'won' by some measurements since they'd have more seats in parliament than they did last time.
