A review of public polling, extensive interviews with a host of his supporters in two states and a new private survey that tracks voting records all point to the conclusion that Mr. Trump has built a broad, demographically and ideologically diverse coalition, constructed around personality, not substance, that bridges demographic and political divides. In doing so, he has effectively insulated himself from the consequences of startling statements that might instantly doom rival candidates.
In poll after poll of Republicans, Mr. Trump leads among women, despite having used terms like “fat pigs” and “disgusting animals” to denigrate some of them. He leads among evangelical Christians, despite saying he had never had a reason to ask God for forgiveness. He leads among moderates and college-educated voters, despite a populist and anti-immigrant message thought to resonate most with conservatives and less-affluent voters. He leads among the most frequent, likely voters, even though his appeal is greatest among those with little history of voting. . . .
His support is not tethered to a single issue or sentiment: immigration, economic anxiety or an anti-establishment mood. Those factors may have created conditions for his candidacy to thrive, but his personality, celebrity and boldness, not merely his populism and policy stances, have let him take advantage of them.
Tellingly, when asked to explain support for Mr. Trump in their own words, voters of varying backgrounds used much the same language, calling him “ballsy” and saying they admired that he “tells it like it is” and relished how he “isn’t politically correct.”
Trumpism, the data and interviews suggest, is an attitude, not an ideology.
The candidate he most resembles, actually, is Barack Obama, circa 2007.
