The conventional wisdom holds that sweeping demographic shifts propelled Barack Obama to the presidency.
So here’s a simple question: Why haven’t these demographics swept Hillary Clinton to a big polling lead and a smooth glide to victory? Donald J. Trump, after all, has alienated just about every growing demographic group and every category that helped push Mr. Obama to victory.
The biggest reason is that demographic change was an overrated contribution to Mr. Obama’s victory, and it will help Mrs. Clinton only at the margins this year. Analysts have conflated all of the effect of higher turnout and percentage of support among nonwhite voters with demographic shifts. In truth, the turnout and support were far more powerful components. CONT.
