Chester County pollbook mishap resulted from human error and flawed systems, report finds
Human error was the primary cause of a pollbook printing issue that forced thousands of voters in Chester County, Pennsylvania, to cast provisional ballots in the 2025 municipal election, according to a report by outside investigators.
Early on on Nov. 4, 2025, voters and election officials realized that the pollbooks — the printed voter lists used to check people in at polling places — didn’t include the names of Chester County’s more than 75,000 unaffiliated and third-party voters. Those voters had to either wait for supplemental pollbooks to be delivered or use a provisional ballot, an option used when there is some question about a voter’s eligibility.
According to the report — from West Chester-based law firm Fleck Eckert Klein McGarry LLC and released Thursday by the county — the “two inexperienced employees” who generated the pollbook files mistakenly selected the option to include “only voters from the major parties.” The report said the employees had “limited election experience, no formal SURE system training, and no direct supervision during a critical task performed under compressed statutory deadlines.” SURE, or the Statewide Uniform Registry of Electors, is Pennsylvania’s voter registration database.
As a result of the error, about 12,600 provisional ballots were cast in the county, accounting for roughly 6.4% of the county’s total vote, more than in any other election in the county’s recent history. The vast majority of the provisional ballots were counted after the county confirmed the voters’ eligibility.
