Philadelphia election officials are gearing up for a steady stream of voters early Tuesday morning.

“The polls will open tomorrow at 7 a,m. and they will be open until 8 p.m. tomorrow night,” said Lisa Deeley, chairperson of Philadelphia city commissioners. “If you are in line at 8 p.m., you’re still able to vote.”

Eyewitness News sat down on election eve with Deeley. She explains what voters can expect once they get to the polls.

“When you get into your polling place, you want to check in with your friendly neighbors who are the election board workers,” Deeley said. “You give them your name, they find you in the poll worker book and then they’ll direct you to a voting system where you can vote in person on the voting machine.”

If you’ve changed your mind and would rather vote in person, you still can.

“If you’re a mail-in voter and you prefer to vote in-person tomorrow, you still have the option to do that,” Deeley said. “What you need to do is bring your entire ballot, the contents just as they were delivered to you, to your polling place, you’ll surrender that ballot to the election board and they will allow you to vote on the voting system.”
