The Short Answer: No, It's About Plurality
To put it simply, New Hampshire does not require a candidate for federal office—that includes U.S. Senator, Representative in Congress, or President—to win a majority of the vote (more than 50%). Instead, the state operates on a plurality voting system. This is often called a 'first-past-the-post' system: the candidate who receives the most votes wins, period. Even if they secure less than 50% of the total vote, as long as they have more votes than any other single candidate, they are declared the winner. This applies to both the state's primary and general elections for federal and most state-level offices.
First-Past-the-Post Explained
Imagine a race with three candidates. Candidate A gets 42% of the vote, Candidate B gets 38%, and Candidate C gets 20%. In a majority system,
no one would win on the first ballot because no one broke the 50% threshold. This would typically trigger a runoff election between the top two finishers, Candidate A and Candidate B. However, in New Hampshire's plurality system, Candidate A wins the election outright with their 42% share. The system is straightforward and delivers a clear winner on election night. Proponents value this simplicity and decisiveness, which aligns with the state’s practical political culture.
Why This System Matters
The use of a plurality system has significant consequences, especially in an era of heightened political polarization and the rise of third-party or independent candidates. A candidate can, and often does, win an election without the support of a majority of voters. In a closely divided race, a third-party candidate can act as a 'spoiler' by drawing a few percentage points of support away from a major party candidate, thereby swinging the election to the other major party nominee. This can lead to winners who a majority of the electorate technically voted against, raising questions about their mandate to govern.
How New Hampshire Differs From Other States
While New Hampshire’s system is common across the U.S., a growing number of states have implemented different rules to ensure a majority winner. Georgia and Louisiana, for instance, require a general election runoff for state and federal races if no candidate secures over 50% of the vote. This ensures the ultimate winner has majority support. Maine and Alaska have adopted ranked-choice voting (RCV), where voters rank candidates in order of preference. If no one wins a majority of first-preference votes, the last-place candidate is eliminated, and their votes are redistributed to their voters' second choices until one candidate achieves a majority. These systems are designed to better reflect the electorate's will and eliminate the 'spoiler effect'.
A Curious Wrinkle for Governor
Interestingly, New Hampshire’s state constitution includes a unique provision for the governor's race that differs from federal races. While a candidate for governor also wins with a plurality, there's a contingency plan if no one achieves it. In the highly unlikely scenario of a tie or a failure to determine a plurality winner, the State Senate and House of Representatives would convene in a joint ballot to choose the governor from the top two vote-getters. This process was more common when the constitution required a majority for governor, a rule changed in 1912 to the current plurality system.
