There's more reason to believe the winner of the Presidential election in Pennsylvania may not be known for days.
While Allegheny County will start the morning of Election Day to pre-canvass mail-in ballots, at least five Pennsylvania Counties confirm they won't start until the next day.
Counties with large populations and larger staffs say they will vote count around the clock. That's not the case in Beaver, Greene, Cumberland, Franklin and Monroe Counties which say they won't start counting mail ballots until the day after.
Beaver County Commission Chair Daniel Camp says they don't have the staff to keep counting through the night.
Ray Murphy, with the group Keystone Votes, says accuracy and lack of interference are more important. "What matters is that counties count the vote transparently and as quickly as they can and meet the deadlines to submit their county's tally to the Department of State."
In a close election, that could mean days of tension and uncertainty.
Allegheny County is among the largest counties planning to count around the clock.]
Prior to heading the the polls on November 3, some voters in Allegheny County will receive letters notifying them of updated information regarding their polling place.
The districts affected include Bethel Park, Braddock Hills, Brentwood, Green Tree, McCandless, Plum and West Mifflin.
Polls open at 7am and remain open until 8pm. Anyone in line at 8pm will be able to vote.
