Plurality voting is notorious for producing winners without majority support in races that have more than two candidates. It can also create spoilers, or losing candidates whose presence in a race alters the outcome, as Ralph Nader’s did in the 2000 presidential election. And it can result in vote-splitting, where similar candidates divide support, paving the way for a less popular winner. This happened in the 2016 Republican primaries when Marco Rubio, Ted Cruz and John Kasich split the anti-Donald Trump vote.
Plurality can also encourage dishonest voting. That happens when voters are pressured to abandon their favorite candidate for one they like less but think can win. In the 2024 elections, for example, voters whose preference for president was Jill Stein, the Green Party nominee, might have instead cast their vote for Democrat Kamala Harris.
An increasingly well-known alternative to plurality voting is ranked choice voting. It’s used statewide in Maine and Alaska and in dozens of municipalities, including New York City.
