Elections based on a plurality system discourage new parties from forming because which statement is most accurate?

• A. a plurality system requires parties to form alliances with other parties to win elections
• B. under this winner-take-all system, no incentive is given for finishing second (or lower)
• C. a plurality system discourages patronage and reduces voter interest in joining a party
• D. a plurality system gives an advantage to savvy political unknowns who can grab the media spotlight

Answer: (B)

This question hinges on how a plurality winner-take-all system shapes party formation. In this setup, the candidate with the most votes wins, even without a majority, across each district. Because there’s no reward for finishing a close second or lower, voters and organizers avoid backing parties unlikely to win. A new party that could only come in behind the leading parties would not gain seats and might even help one of the major parties defeat the other by splitting the vote—the spoiler effect. So there’s little incentive to form or sustain a third party, which encourages a two-party system over time. The other statements don’t capture this mechanism: alliances aren’t required by the system, patronage and voter interest aren’t the core outcome here, and simply having media spotlight doesn’t overcome the structural incentive to consolidate around the major parties.
