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

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

The [Hillary] Clinton campaign's recent travel schedule shows how seriously it takes this problem. She and her surrogates have held rallies in cities like Philadelphia, Detroit and Cleveland, trying to boost turnout among African-Americans.

People like Ted Cruz, who has tried to position himself as the best second choice for [Donald] Trump supporters, wouldn't condemn him.

For a long time, many Republicans thought if they just took two aspirin and laid down, [Donald] Trump would go away.

A big win for [Hillary] Clinton would allow her to claim that the country rejected Trumpism, while a narrow win leaves her limping into office with the highest unfavorable ratings for any new president.

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