The Senate, Small Parties and the Balance of Power

Abstract

Abstract The recent change to the number of senators to be elected from each state will alter the quota for election of senators in a way which will have the consequence of making it harder for minor party and independent candidates to secure representation in the Senate. This, in turn, will have the effect of reducing the likelihood that minor party and independent senators will hold the balance of power in the Senate with a consequent decline in the ability of the chamber to continue to make the major contribution to the governmental process at the national level that it has done in recent times. This proposition is examined first in terms of the logic of the quota system of proportional representation given various patterns of voting support for large and small parties, and secondly in terms of the performance of minor party and independent candidates in Senate elections since 1949.
