We have what is probably the final data for tonight. (Actually, see below. Maybe not.) Almost all the final election day votes were reported just a short time ago. Those ballots brought Connor Lamb’s lead to just under 100 votes. But then a short time later, Allegheny County reported its absentee ballots. Those came in overwhelmingly for Lamb, leaving him with an 847 vote lead. The remaining counties are all red counties and all plan to count their absentee votes tomorrow. It looks hard for Saccone to make up that margin. But it’s definitely possible.
The latest we heard is that one of those counties may count their absentee ballots tonight, just because it’s so close. If that happens, we might have a pretty clear sense tonight of who won. Stay tuned.
Late Update: Watching the number crunchers whose opinions I most respect, the consensus seems to be that Lamb wins, absent sole counting error as yet unknown.
