Georgia: The growing non-white population in the Atlanta metro, the potential for the black voter bloc to flex its muscles, and suburban whites possibly shifting Dem on the presidential level (not necessarily locally)
2016: Trump +5, 2020: Trump +2, 2024: Dem +5, 2028: Dem +8 (Stacey Abrams on the ballot 
), 2032: Dem +10
Arizona: Hispanic population aging into the electorate, California transplants
2016: Trump +4, 2020: Dem +2, 2024: Dem +7, 2028: Dem +10, 2032: Dem +12
I'm not well versed enough about the population shifts, age and racial demographics in the Mid-west to make completely accurate predictions, but I feel like for the GOP it would be Wisconsin and Ohio, though I may be wrong about them (especially Ohio-- which I don't pay attention to at all lol).
Pretty much this. But I think that Ohio and Wisconsin remain within reach for the Democrats. Iowa might be a different story because of the high number of rural voters. I wonder that it actually voted so frequently Democratic in past cycles, even when a Republican was elected.
