This ignores demographic differences between states. The shifts that theoretically pull a GA or a NV into the R column may or may not have much of an impact in 80%+ white and much older states like WI, MI, and PA; and could even cause drift in the opposite direction.
I think GA goes narrowly R this cycle. I think NV does too. I know @Js1 will roast me for that but the GOP has had some intermittent success in NV over the past decade, most recently a Governor's race in 2022, and the coalitions that delivered each state for Biden appear to have legitimate fractures.
AZ is a complete wildcard. Fundamentally it's not far from NV but the prominence of abortion an the absolute toxicity of the state GOP bring it back into tossup category. Gallego is also a strong Senate candidate and his campaign could elevate Biden a bit.
I don't see Trump finding 100k+ votes in MI or PA, even with the mess in Gaza. WI is one of the 2-3 legitimately 50-50 states in the country and could go either way, but Democrats there have been on a roll and have a generational opportunity at the state level.
I think it will ultimately come down to WI and AZ. I think Biden needs both because Trump will put pressure on NE to go winner take all, the state level GOP will give in very late in the cycle and ram it through in a special session, and Maine will not have the ability or the appetite to respond in kind.
Senate goes GOP 51-49 and the House is Democratic - not by a huge margin but more cushion than the GOP has now.
