Final answer:
Duverger's law claims that proportional representation elections favor a multi-party system. In proportional representation, the proportional translation of votes into seats allows a diverse range of political voices to be represented.
Step-by-step explanation:
Duverger's law posits that proportional representation elections are conducive to the development of a multi-party system.
Proportional representation, an electoral mechanism wherein a party's legislative seat allocation corresponds to its share of the popular vote, facilitates the inclusion of smaller parties in the government.
This stands in contrast to plurality systems with single-member districts, which often foster a two-party dominance.
In proportional representation, the proportional translation of votes into seats allows a diverse range of political voices to be represented, promoting a more pluralistic political landscape.
Unlike the winner-takes-all nature of plurality systems, where the leading party secures all representation in a given district, proportional representation encourages a broader spectrum of political ideologies and parties to have a meaningful presence in the legislative body, thereby fostering a multi-party political environment.
