Why has North Carolina and Virginia trended Democrat 4 times in a row now?

[GGSETTER]

The entire southern east coast from Atlanta up to DC seems to be developing into a second BosWash area.   The Metros are among the fastest growing in the country and it's increasingly developing a "digital economy".   

South Carolina doesn't have any large metro to drive this change so it's going slower than the other three.

This is distinct from Florida where the main drivers to change are Latino immigration and Retiree migration. 

Except Virginia and Georgia were the only 2 Southern States that didn't get Redder in 2016. Every other state kim Florida and North Carolina got more Red so......

NC still trended Dem in 2016 but very very lightly.

Are you sure? I don't believe it did.

Both states are becoming more urbanized and more educated, though Virginia is becoming more Democratic faster because of the high density of Federal workers in NoVa. North Carolina is a bit more like Florida in that its population trends are somewhat canceling each other out, though the Dem trend is slightly faster.

Florida is becoming more and more Republican and has been doing so for years.
