Woukd just Georgia decertifying drop Biden Below 270?
No.
We would need three, four states to seal the deal.
GA(16) PA (20) and AZ (11) would do it. Best chance in those 3 states to win.
It stands at Biden 303, Trump 232 right now.
GA and PA would bring them within one vote: Trump 268,Biden 267. AZ would bring Trump over 270. So would NV (6).
