The Core Principle: A Tale of Two Thresholds
When it comes to close elections in Delaware, the magic formula often involves two numbers: 1,000 votes and one-half of one percent (0.5%). For most state and county general elections, a recount is triggered if the vote margin between the top two candidates is less than 1,000 votes or less than 0.5% of the total votes cast for those two candidates, whichever is smaller. This 'whichever is less' clause is critical. In a high-turnout statewide race with 400,000 votes cast, 0.5% would be 2,000 votes, so the 1,000-vote rule would apply. In a lower-turnout local race with 10,000 votes, 0.5% is just 50 votes, so that much smaller margin becomes the trigger. This dual system is designed to provide a reasonable threshold that scales with the size of the electorate.
State Legislative and County Races: Truly Automatic
The term 'automatic' most accurately applies to general elections for the Delaware General Assembly (State Senator and State Representative) and county-level offices. If the final, certified vote count shows a margin within the 'lesser of 1,000 votes or 0.5%' window, the Superior Court, which acts as the Board of Canvass, is required to conduct a recount at state expense. No one needs to request it; the process is initiated automatically as part of the formal vote certification. This ensures that in local and legislative races, where even a handful of votes can determine the winner and community representation, an extra layer of verification is built directly into the process without requiring action from the candidates themselves.
Statewide Races: A Recount by Request
Here's where the process differs slightly. For top-of-the-ticket statewide offices like Governor, U.S. Senator, or Attorney General, a recount is not technically 'automatic'. Instead, if the vote margin falls within that same threshold—less than 1,000 votes or 0.5%, whichever is smaller—the losing candidate has the right to apply to the court for a full recount at state expense. While it requires the candidate to formally request it, the state still covers the cost, acknowledging that such a close margin warrants a second look. This request must be made before the Board of Canvass officially adjourns and certifies the election. So, while the trigger is the same, the mechanism for statewide races involves an extra step initiated by the candidate.
Primaries and Municipal Elections: Separate Rules
Delaware law also provides for recounts in other types of elections, with slightly different procedures. In primary elections, the rules mirror the general election framework: for a statewide contest, a margin of less than 1,000 votes triggers a recount, while for any other primary contest (like for a legislative seat), the trigger is a margin of less than 0.5% of the votes cast for the top two candidates. For municipal elections outside of Wilmington, the rule is simpler: if the difference between the top two candidates is 0.5% or less of the total votes cast for the office, the municipal Board of Elections must recount the ballots. In races where voters select more than one candidate, the recount is triggered if the margin between the last winner and the first loser is within that 0.5% threshold.
A Recent Push for a Simpler System
The complexity of these varied rules has not gone unnoticed. Following an extremely close primary race in 2024, where a 12-vote margin was not enough to trigger a recount under the existing formula, legislation was introduced in 2025 to simplify the system. The proposed change, known as House Bill 86, sought to establish a uniform 1% margin to trigger an automatic recount across most primary and general elections, from statewide offices down to municipal races. Proponents argued that a single, clear threshold would reduce public confusion and make the process more consistent. While the long-standing rules remain in effect, this legislative effort highlights an ongoing conversation in Delaware about how best to balance efficiency with the unwavering need for electoral accuracy.
