Trump still has a chance in AZ, as in NV. He could also possibly flip WI. MI seems less likely.
Trump has outperformed predictions across the board. The same is true for down-ballot races. Some were predicting Democrats to pick up as many as 15 House seats, and there was a prediction on election night that Democrats would pick up 5 House seats, however Republicans ended up gaining at least 5 House seats, and it seems likely they will flip as many as an additional 7 House seats. Democrats were also favored to flip the Senate, however, that also looks especially unlikely at this time.
I'm not optimistic at all. Seems like we're getting our hopes up for nothing. Fox News was the first org. to call AZ then AP called AZ. Fox covered this election fairly and I don't think they'd risk calling AZ early.
Nate Silver talked about it being too early to call which gave me hope but being down 3 points + is what bothers me.
I would say that NV or AZ going Trump's way is more likely than WI or MI. NV (and to a lesser extent, AZ) has an economy that is heavily based on tourism, and tourism is not possible when the country is locked down. Trump may perform better in Reno and Vegas than he might do in other cities because of the tourism employees voting Trump to avoid lockdown related layoffs and casinos going out of business that would happen under a Biden administration.
In AZ, it will really come down to Maricopa county. I understand he needs about 57% of the remaining vote in Maricopa county to stay competitive in AZ.
Flipping one of AZ, NV, WI or MI would likely put Trump back in the White House until 2024. It may come down to a court case making it to the SC. Trump can also technically still win even if he does not flip any of those states, but otherwise runs the table (takes PA, GA, and NC). If Trump were to stop any of AZ, NV, WI, or MI from casting their electrical votes, Biden would not make it to 270, and Congress would elect the President with each state getting one vote, and Republicans hold the advantage.
