At this point all the PA polls saying the same thing. 5-7 point Biden lead. That’s the ballpark right there, unless everyone is way off.
And it would have to be "off more than in 2016" off, and on top of that, we can see through early voting that more Dem voters and Dem-leaning voters are voting across pretty much every state - not just PA, but FL and AZ.
It would take literal changing of or discarding of votes to do anything, and even then, in TX the all-Republican Supreme Court let a bunch of Harris County drive-up votes that are going to be heavily Dem stand when they were challenged by the GOP.
This isn't to say that Biden is a lock because nothing is ever a lock in this country, but the numbers are basically telling us how this is going to go - 290 EVs at worst for Biden, and probably more than that.
