Over the weekend, President Trump said he wanted to see election results by the end of Election Day and suggested that Democrats may try to steal the election if the votes weren’t counted by then.

But with record numbers of mail-in ballots this year  — more than 3 million voters requested them —  and the fact that Pennsylvania is among a handful of states that won’t be able to start counting votes until Election Day, it’s highly unlikely the commonwealth will be able to process its ballots in one day. 

Our guest, WHYY reporter Aaron Moselle, has been digging into ballot-counting operations in Philadelphia and the suburbs and explains why results will take longer in a battleground state that could decide this election.
