from The City Journal, Trump and the American Divide by Victor Davis Hanson:
As the nation became more urban and its wealth soared, the old Democratic commitment from the Roosevelt era to much of rural America—construction of water projects, rail, highways, land banks, and universities; deference to traditional values; and Grapes of Wrath–like empathy—has largely been forgotten. A confident, upbeat urban America promoted its ever more radical culture without worrying much about its effects on a mostly distant and silent small-town other. In 2008, gay marriage and women in combat were opposed, at least rhetorically, by both Barack Obama and Hillary Clinton in their respective presidential campaigns. By 2016, mere skepticism on these issues was viewed by urban elites as reactionary ignorance. In other words, it was bad enough that rural America was getting left behind economically; adding insult to injury, elite America (which is Democrat America) openly caricatured rural citizens’ traditional views and tried to force its own values on them. Lena Dunham’s loud sexual politics and Beyoncé’s uncritical evocation of the Black Panthers resonated in blue cities and on the coasts, not in the heartland. Only in today’s bifurcated America could billion-dollar sports conglomerates fail to sense that second-string San Francisco 49ers quarterback Colin Kaepernick’s protests of the national anthem would turn off a sizable percentage of the National Football League’s viewing audience, which is disproportionately conservative and middle American. These cultural themes, too, Trump addressed forcefully.
This is a critical observation. The New Deal and its infrastructure spending benefited the heartlands and made them loyal Democrats for generations. With this election that bond is broken and the hammer was identity politics. It will not be easily restored.
