“We have no founded complaints of intimidation. No founded complaints of voter fraud. We have no walking apocalypse zombies walking all over town. We don’t have that and I’m very thankful. But again we are here to ensure that every Philadelphian that wants to vote can do so unencumbered, unimpeded, without threat or harassment by anyone.

As of 4:45 p.m. more than 85 election complaints had been called in, 34 of which the District Attorney’s office is investigating. Thirteen of those complaints involved complaints of electioneering — campaigning within the polling area which is not allowed within 10 feet of the polling entrance. There have been 10 complaints for machine issues or malfunctions and 15 calls for voter assistance problems. The rest of the complaints have been called in for various issues.
