Sore Loser Laws and Notable Candidacies in US Elections
In the complex landscape of American politics, a sore loser law is a regulation that prohibits a candidate who has lost a primary election from running as an independent or third-party candidate in the subsequent general election. These laws are designed to ensure party stability and prevent candidates from bypassing the primary process after failing to secure their party's nomination.
While these laws are common, their application varies significantly by state, leading to high-profile legal battles and unconventional campaign strategies. From Supreme Court rulings to surprising general election victories, the tension between party rules and individual candidacy has shaped numerous contests.
Key Facts
- Sore loser laws prevent primary losers from running in the general election under a different affiliation.
- The U.S. Supreme Court upheld the validity of these laws in the case of Storer v. Brown.
- Some states, such as New York and Iowa, have historically lacked these restrictions, allowing candidates more flexibility.
- Candidates barred from the ballot by sore loser laws may still be eligible to run as write-in candidates.
Legal Precedents and State Variations
The legality of sore loser laws was tested in 1972 during the California elections. Two congressional candidates who lost their primaries challenged the state's restrictions. The matter reached the Supreme Court, which ruled in Storer v. Brown, upholding the law and confirming the state's right to restrict candidates who had already lost a primary.
Conversely, the absence of such laws can drastically alter an election's outcome. In the 2006 Connecticut Senate election, Joe Lieberman was defeated by Ned Lamont in the Democratic primary. Because Connecticut was one of only three states at the time (alongside New York and Iowa) without a sore loser law, Lieberman successfully ran as an independent and won the general election.
Challenges in Presidential and Senate Races
The Gary Johnson Case in Michigan
Sore loser laws can sometimes be triggered by administrative errors. In 2012, Gary Johnson was three minutes late in withdrawing from the Michigan Republican Primary, which left him on the ballot. Consequently, he was denied ballot access as a Libertarian candidate.
The Libertarian Party attempted a unique legal maneuver, proposing that a Texas businessman also named Gary Johnson stand in as the candidate. However, a U.S. District judge denied the motion. Johnson eventually ran as a certified write-in candidate in Michigan, receiving 7,774 votes.
The 2018 West Virginia Senate Race
In 2018, Don Blankenship finished third in the West Virginia Republican Senate primary with just under 20% of the vote. Seeking an alternative route, Blankenship attempted to run as a candidate for the Constitution Party. While the Supreme Court of Appeals of West Virginia denied his ballot access, he remained eligible to appear as a write-in candidate.
Local and Municipal Impact
The 2021 Buffalo Mayoral Election
The impact of primary losses is not limited to federal races. In the 2021 Buffalo mayoral election, incumbent mayor Byron Brown lost the Democratic Primary to India Walton by 7.02%. Despite the loss, Brown announced his intention to run as a write-in candidate. In a surprising turn, Brown defeated Walton in the general election by 19.17%.
The 2025 New York City Mayoral Election
In the 2025 New York City Democratic mayoral primary, Zohran Mamdani emerged as the presumptive nominee after defeating Andrew Cuomo and other challengers. Cuomo had proactively formed the Fight and Deliver Party prior to the primary to ensure a path to the general election. Despite his primary defeat, Cuomo continued his campaign and ran in the general election, though he ultimately lost to Mamdani on November 4, 2025.
