The Polls May Be Underestimating Trump's Support (Henry Olsen) from the Atlantic
"Data suggests the appeal of anti-immigrant policies to working-class voters is much deeper than most American elites want to believe. And because Trump draws the bulk of his support from less-educated, working- and middle-class voters, he may be positioned to do even better still—for now. Polling data from Europe shows that parties with similar voter profiles to Trump’s consistently do better in both online polls and at the ballot box than in live-interview polling. And currently Trump is far ahead online."
