Ross Douthat's column in yesterday's New York Times is today's must-read.

Headlined "From Obama to Trump," the column will explain a lot to all of us who are sitting around asking, "What happened to my country?"

The theme is something I've been trying to feel my way towards expressing over the last few years, talking on the blog about how our flinty American founders would have been shocked by the personality cult into which we have descended when it comes to picking presidents.

Douthat nails it:

But Trumpism is also a creature of the late Obama era, irrupting after eight years when a charismatic liberal president has dominated the cultural landscape and set the agenda for national debates. President Obama didn’t give us Trump in any kind of Machiavellian or deliberate fashion. But it isn’t an accident that this is the way the Obama era ends — with a reality TV demagogue leading a populist, nationalist revolt.

First, the reality TV element in Trump’s campaign is a kind of fun-house-mirror version of the celebrity-saturated Obama effort in 2008. Presidential politics has long had an escalating celebrity component, a cultish side that’s grown ever-more-conspicuous with time. But the first Obama campaign raised the bar. The quasi-religious imagery and rhetoric, the Great Man iconography and pillared sets, the Oprah endorsement and Will.i.am music video and the Hollywood stars pledging allegiance — it was presidential politics as one part Aaron Sorkin-scripted liturgy, one part prestige movie’s Oscar campaign.

And it worked. But because it worked, now we have the nearly-inevitable next step: presidential politics as a season of “Survivor” or, well, “The Apprentice,” with the same celebrity factor as Obama’s ’08 run, but with his campaign’s high-middlebrow pretensions stripped away. If Obama proved that you can run a presidential campaign as an aspirational cult of personality, in which a Sarah Silverman endorsement counts for as much as a governor or congressman’s support, Trump is proving that you don’t need Silverman to shout “the Aristocrats!” and have people eat it up.

He’s also proving, in his bullying, overpromising style, that voters are increasingly habituated to the idea of an ever more imperial presidency — which is also a trend that Obama’s choices have accelerated. Having once campaigned against his predecessor’s power grabs, the current president has expanded executive authority along almost every dimension: launching wars without congressional approval, claiming the power to assassinate American citizens, and using every available end-around to make domestic policy without any support from Congress.

I post this item not as a way to look at Donald Trump or Barack Obama or any other politician but as a way to look at ourselves.
