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

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.

Yes, the presidential race is very close, and some public polls show it getting closer as we go into the final hours, but in one sense it's actually been stable for months.

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

The GOP establishment, in particular, is facing a pick-your-poison kind of decision. Many establishment Republicans dislike [Ted] Cruz personally. He has no Senate endorsements.

The Senate is the big prize. Until recently, Democrats felt confident they could get the four seats they needed to take back control if [Hillary] Clinton is in the White House and Vice President Tim Kaine held the tie-breaking vote.

Republican voters are coalescing behind [Donald] Trump, but many Republican elected officials still say they can't support him.
