That's true. It's not impossible to imagine Biden actually winning GA by 3.6%, especially with the D trends we'll likely see in the ATL metro area.
PA is also surprisingly less pro-Biden than I would have expected. If metro Philly and Pittsburgh are expected and NE PA is swinging 10+ points to the Dems based on GOP internal polls, there would have to be some counter trends in some other parts of the state for the state to only be +4.4 Biden.
The GA numbers are surprisingly pro-Biden. That said, the Trump campaign has been spending time in the Macon, GA area this week so maybe their polls are picking up on the same trendlines here. The other state numbers seem pretty reasonable.
I don't think GA votes that different from WI/MI (GA was +5 GOP and WI +1GOP last time and Georgia has only trended more democrat since then).
