The Chester County Board of Elections says it was human error -- not misconduct -- that led to all independent or third-party voters being omitted from election day poll books last November.
Law firm Fleck, Eckert, and Klein determined that someone using the system that generates poll books incorrectly selected an option to include "only voters from the major parties".
Chester County Chief Experience Officer Megan Moser is recommending increased safeguards on the system that generates poll books to prevent similar mistakes in the future.
She's also recommending increased training, more verification, and the creation of a contingency plan for future mishaps, among other advisories.
Nearly one-fifth of the county's electorate was affected. Registered voters whose names did not appear in poll books were given the chance to submit provisional ballots. And all 230 polling locations in the county remained open two extra hours thanks to a judicially approved extension.
