The enthusiasm for [Donald] Trump had gone up. The net result was it made people more supportive of him.

What does [Hillary] Clinton do if she loses? Concede? Blame the Russians? Or the FBI?

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

If [Donald] Trump loses narrowly, it will make it much harder for the GOP to unify. Under that scenario, the Trumpists are likely to argue that the election was lost because the Republican establishment failed to rally around the choice their own voters made.

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 establishment is divorcing itself from its base - from voters who are choosing a candidate who says he stands for things that are anathema to the establishment.

Romney still enjoys the Republicans' traditional advantage among voters who are veterans, but the Obama campaign is confident it can chip away at that.
