Even if [Donald] Trump concedes, some of his supporters have promised to take up arms against [Hillary] Clinton.

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.

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

[Donald Trump ] would make history in so many ways because he is a candidate who eschewed the traditional arts of political campaigns, including field organization, traditional advertising, debate preparation and policy knowledge.

Meanwhile, there are some traditional battleground states - like Ohio and Iowa - that are becoming older, whiter and less educated. That's turning them from true battlegrounds into more reliable red states.

The winner's margin of victory also matters. If it's a squeaker, that will make the lessons learned for both parties much murkier.
