If one candidate wins an election in Pennsylvania by a 0.5 percent margin or lower, the state will recount the ballots, regardless of whether a request is made. But with new ballots in from Allegheny County, which is home to Pittsburgh, Biden is now up by 0.74 percent. Theoretically, the number could shrink with more tallying underway, but Biden’s lead is expected to continue going up, so President Trump or Pennsylvania voters will have to seek out a recount should he desire one.
