As those states and others in the South and West become more diverse and educated, they will become harder for the Republican Party - in its current form - to win.

[Hillary] Clinton has also struggled with key groups of voters.

This year [2016], however, polls show [Hillary] Clinton winning white college-educated voters by double digits.

No one is predicting that the Democrats will get the 30 pickups they need to take back the House majority.

The lesson is that voters in both parties are in a very anti-establishment, populist mood. Hillary Clinton is the establishment candidate.

If [Hillary] Clinton can come close in those two traditionally red states, it will be because of the diverse, educated populations around Atlanta and Phoenix. And it will be a sign that Arizona and Georgia are on their way to becoming the new battleground states.

The aftermath of this extraordinary election [2016] could be just as surprising as the race itself.
