Document Summary
M = 1, it is single : all else being equal, a higher m is going to give you a more proportional system, the vote share is closer to the seat share, example: Allocation rules: how you translate votes into seats. Nv goes down: strategic voting: in order to effect the outcome of the election, you cast a ballot for a contestant that is not your top preference. People do this to avoid a wasted vote : the decisions that elites make are also strategic. Mistaken direction of causality: he has it backwards . Electoral system not important: social cleavages might be what is driving thing, cox"s response to electoral system not important argument- study of bicameralism. Rules are important too; same country, same number of cleavages with different rules will lead to different numbers of parties. Restrictive rules can halt the effect of cleavages. Fundamentally, the duverger"s law logic is about there being two parties at the district level.
