Watch out for Philly....They always save the heavy Dem areas with huge populations until all the other numbers are in...
because the numbers are so huge in those districts...pretty easy to cheat.
Actually, philly usually reports early (*until the mail-in ballot surge in 2020). In 2016 and in earlier senate races where toomey won, the first reports were hugely dem (Philly) that were finally overcome late in the evening as the more rural areas finished reporting. One reason that Pa was mostly the state that finally put Trump over the top in 2016 as he pulled ahead late.
you can watch the archived election night coverage on youtube or elsewhere to confirm this.
