Philadelphia District Attorney Seth Williams charged four poll workers with election fraud yesterday.

Election judge Sandra Lee and machine inspector Gregory Thomas, along with inspectors James Collins and Alexia Harding, will face charges of fraud and tampering, among others, after malpractices following the 2014 general election.

Lee and Thomas, both 60, as well as Collins, 71, were arrested for repeat voting at elections, tampering with public records, fraud by election officers, conspiracy, failure to perform duty, obstructing law enforcement and other charges. Harding has been charged with false swearing and unsworn falsification to authorities.

After polling closed last November 4th, the four poll workers noticed an inconsistency in their numbers. The precinct had six more signatures than votes recorded on the machines.

This is a not uncommon problem, many voters don’t properly follow the instructions. The poll workers, however, came up with a rather novel solution.

To fix the inequity, Collins stood at the front of the voting booth and registered the six votes while Thomas was behind the machine. Investigators said a poll watcher witnessed this entire sequence of events.

Additionally, three of the four workers also reside outside the area where they worked the polls.

“There’s no legally justifiable reason to vote multiple times, and you cannot falsely certify that you live in a particular ward and division in order to work the polls and collect a check,” D.A. Williams said in a statement. “Our democracy rests on free and fair elections, but it also relies on the fact that they are conducted properly, which is why these four individuals deserve to be arrested for what they did.”
