I don't think the Dems can possibly dig up ~700,000 votes to pull ahead in PA. The votes just aren't there.
I don't think there's enough vote left in NC and GA to give those states to the Dems either. Those precincts are in already.
If more vote come in for WI and MI, looking at the counties remaining, a lot of that vote is going to go to Trump too.
I understand that the Rust Belt states have more time for mail-ins to come in, but there's no reason not to call GA and NC. That just looks like the governors and the media are being disingenuous.
