Assuming a very competitive election, democrats should focus on in the following order:
1. Pennsylvania
2. Florida
3. Wisconsin
4. Georgia
5. Michigan
6. Minnesota
7. North Carolina
8. Nevada
9. Arizona
10 Maine
11. New Hampshire
Georgia is trending left faster than most states (Mississippi is probably trending faster but it's too far gone right now). Very big age gap in voting. Young whites are getting less polarized, and most young people there are miniorities too. A lot of more liberal people from new england are moving down to Georgia as well. I don't really see much room for growth in Arizona or North Carolina. Iowa and Ohio are going to be very hard to win without a big victory.
Georgia is prioritized more than Nevada / NH / Maine because these states don't have much electoral votes.
Michigan shouldn't be too hard to win as long as /some/ resources are put into the state and the messaging isn't too bad. Minnesota seems like it could be a longterm problem for democrats but I think they will be okay for a little bit longer as long as they put in more resources.
PA and Wisconsin are a bit tougher, and Florida is always a tough state to win even though the population will probably be less than 60% white by the time 2020 comes around.
