The primary conflict structuring the two parties involves questions of national identity, race, and morality, while the traditional conflict over economics, though still important, is less divisive now than it used to be. This has the potential to reshape the party coalitions.
By making questions of national identity more salient, Donald Trump succeeded in winning over populists (socially conservative, economically liberal voters) who had previously voted for Democrats.
Among populists who voted for Obama, Clinton did terribly. She held onto only 6 in 10 of these voters (59 percent). Trump picked up 27 percent of these voters, and the remaining 14 percent didnt vote for either major party candidate.
