Arizona's population growth comes from the upper midwest, the northeast and the biggest source is California and the Northwest. It is still right at the top in terms of fast growing. The Latino population is also burgeoning, the central school districts in Pnoenix and Tucson is 70% Latino enrollment. Georgia is also growing, not only with a Latino population as well, but also from the Northeast, and the influx tends to be more Democratic.
North Carolina has many of the same characteristics. I think working all three states and helping the local, county and state branches of the party reach out, it could be turned.
I would also, perhaps surprisingly, say Texas. Same thing there, large numbers of Latinos, the state is on the verge of being a majority minority population with African Americans, Latinos and Asians outnumbering whites. Also, lots of in-migration there from California, the upper midwest and Northeast, with a lot of those people being Democrats. The state party needs to figure out how to turn all those constituencies out.
Some work to bring about party unity in Southeastern Wisconsin would lead to that state being reliably blue instead of a question mark. Racine and Kenosha County were once predominantly Democratic, but that shifted in 2016. The African American and Latino population there, added to the white liberals, is a majority. But the voter registration has tapered off. I knocked on doors there during the last two election cycles and they are larger than most of the rural counties in the state. If Democrats can win there, they can flip the state legislature, undo gerrymandering that is the only reason Republicans have a legislative majority, and make a difference. Looks good for 2024 as it is.
If we get what once was the bread and butter of the party back, the working class, that opens the door to winning in places like Ohio and Missouri.
