Should Democrats target AZ and GA in 2020?
Both state trended Democratic despite Hillary being a terrible candidate.
In fact, AZ and GA were closer than IA and OH.
I think you're ignoring that Trump was also a poor candidate, especially for these two states that have large metro areas with a large suburban white population that will likely swing back to the GOP in 2020. Arizona is more promising for Democrats than Georgia.
A "poor candidate" doesn't crack the electoral walls in WI, MI, and PA. That's not the resume of a "poor candidate".
I agree that AZ is more promising than GA, but GA is increasing its black population at a rapid rate, and it's a more middle class black population that votes more often. It's white population is also changing, and becoming (slowly) more liberal, as white working professionals move into metro Atlanta.

The white vote is a little flexible it seems in Georgia, at least in Atlanta.
