9.2 The two-party system  (Page 3/19)

In a proportional electoral system, however, parties advertise who is on their candidate list and voters pick a party. Then, legislative seats are doled out to the parties based on the proportion of support each party receives. While the Green Party in the United States might not win a single congressional seat in some years thanks to plurality voting, in a proportional system, it stands a chance to get a few seats in the legislature regardless. For example, assume the Green Party gets 7 percent of the vote. In the United States, 7 percent will never be enough to win a single seat, shutting the Green candidates out of Congress entirely, whereas in a proportional system, the Green Party will get 7 percent of the total number of legislative seats available. Hence, it could get a foothold for its issues and perhaps increase its support over time. But with plurality voting, it doesn’t stand a chance.

Third parties, often born of frustration with the current system, attract supporters from one or both of the existing parties during an election but fail to attract enough votes to win. After the election is over, supporters experience remorse when their least-favorite candidate wins instead. For example, in the 2000 election, Ralph Nader ran for president as the candidate of the Green Party. Nader, a longtime consumer activist concerned with environmental issues and social justice, attracted many votes from people who usually voted for Democratic candidates. This has caused some to claim that Democratic nominee Al Gore lost the 2000 election to Republican George W. Bush, because Nader won Democratic votes in Florida that might otherwise have gone to Gore ( [link] ).

Abandoning plurality voting, even if the winner-take-all election were kept, would almost certainly increase the number of parties from which voters could choose. The easiest switch would be to a majoritarian voting    scheme, in which a candidate wins only if he or she enjoys the support of a majority of voters. If no candidate wins a majority in the first round of voting, a run-off election is held among the top contenders. Some states conduct their primary elections within the two major political parties in this way.

A second way to increase the number of parties in the U.S. system is to abandon the winner-take-all approach. Rather than allowing voters to pick their representatives directly, many democracies have chosen to have voters pick their preferred party and allow the party to select the individuals who serve in government. The argument for this method is that it is ultimately the party and not the individual who will influence policy. Under this model of proportional representation    , legislative seats are allocated to competing parties based on the total share of votes they receive in the election. As a result, any given election can have multiple winners, and voters who might prefer a smaller party over a major one have a chance to be represented in government ( [link] ).
