Must be some misunderstanding here. Because the surplus votes of elected candidates and the votes of eliminated candidates are transferable, the votes will progressively concentrate onto the appropriate number of candidates to represent each group proportionately. > That and all STV's other extreme flaws is why any of the > other better proportional systems are more proportional and > also better in a host of other ways. Proportionality is dependent solely on district magnitude. For the same district magnitude, STV-PR is as proportional as any other PR voting system - no more, but no less. "Extreme flaws" and "better" both require definition and exposition. For many voters, the ability to rank all the candidates freely on any basis whatsoever makes STV-PR "better" than any other PR voting system. One reason why these voters consider that "better" is the effects it can have on the relationships between the elected members and the local voters, between the elected members and their parties, and between the elected assembly and the executive, especially where the executive is based within the assembly (as in "parliamentary" system). These "political" effects (beyond simple PR) are important considerations, especially from the voters' perspective. James Gilmour No virus found in this outgoing message.
