Basically, the Midwest splits. Michigan flips back because it was super close, so does PA, but WI and OH stay Republican. Arizona and Georgia flipping as well as Florida, NC, and NE-02 indicates a significant win for the Democratic candidate, which means an unpopular President Trump in 2020. Indiana votes Dem because of its anti-incumbent streak, which Ohio, Iowa, and Wisconsin lack.
Alternatively:
Almost the same map, but the flip of Wisconsin and Iowa indicate that Ohio stands alone among the midwestern states. In this case, Ohio and Indiana converge, as they've been doing in Trump approval polls. Both states are decided by razor-thin margins, such that they're the two states that voted the closest in the entire nation and maybe even take a couple days to call. However, the difference in percentage just happens to be on opposite sides of the partisan dividing line.
