Have a hard time believing reports there are only 120k uncounted ballots remaining in Philadelphia. That would put it at 695k, leaving it short of the 707k total votes cast in 2016.

Turnout declines aren't happening anywhere in PA, including Pittsburgh...

In other words, I'm extremely skeptical that estimate is accurate. Nonetheless, even if it were borne out, it wouldn't alter my thinking on who's likely to finish ahead.

If Philadephia's turnout was in line with similar cities (and there's no real reason to believe it would be way out of line w/ Detroit, Milwaukee, etc.), there might be 200k-250k ballots left to count there - in which case Biden could take the statewide lead w/ Philly alone.

Of course, there are plenty of other PA counties besides Philly where Biden is still poised to gain a *lot* of ground w/ mail ballots. Delaware, Lehigh, Cumberland, Bucks, Monroe, Centre, Allegheny to name a few. This isn't a nail-biter, imo.
