Conventional wisdom — at least as defined by MSNBC — dictates that Donald Trump has offended so many potential voters that Hillary Clinton is virtually guaranteed to sweep into the White House in a tide of progressive, populist unity.

But what if Trump’s outrageousness truly captures America’s current cultural climate — and Clinton’s carefully curated “kumbaya” coalition is actually the outlier?

It’s not so crazy. And in fact, it’s a climate liberals should recognize: Trump is doing what Democrats have long claimed to do by giving voice to the voiceless.

And as much as Trump might alienate and appall, his iconoclastic campaign aligns with what many across America are already thinking. It’s a stark (if, for many, disheartening) reading of the nation’s social barometer.

But one that Clinton ignores at her own — and her party’s — peril.

According to a series of recent studies, “racial anxiety” more than economic uncertainty is the key driver of potential Trump support. Polls by both The Washington Post and Hamilton College political scientist Philip Klinkner reveal that more than 40 percent of Trump fans believed white peoples’ struggles resulted from “preferences for blacks and Hispanics.”

But it’s about more than race. Trump is speaking for a large segment of Americans who’ve been silenced by an over-reaching identity-politics industry.

At the heart of that resentment is a sense of shame and alienation — a sort of social ghettoization. How else to explain the recent arrival of match-making site TrumpSingles.com for Trump supporters afraid to disclose their candidate-status to potential dates?

Some will view these sentiments as whiny and entitled — “privileged,” to use the lefty jargon. But that’s a silly term to describe voters who are largely working-class and non-college-educated. More important, just labeling these feelings doesn’t make them go away — and they’ve already helped make this the most unpredictable presidential election in recent memory.

Others may see this “racial anxiety” as farcical. But it is, in a sense, almost inevitable. Fed up with the preachy do-goodism and blanket-blaming of the elite, many poorer whites — along with a fair number of everyone else — view Trump as a latter-day prophet ready to rescue them from a demonizing, attack-hungry left.

Folks uncomfortable with all-access bathrooms are called “transphobes.” Even gays who opt to only date within their race are suddenly bigots. Men — all men — perpetuate “rape culture”; every cop is a likely kid-killer; and no religion — no matter its path of mayhem or destruction — can ever be labeled terror-prone or fundamentalist. Everyone (at every moment) must be affirmed and uplifted — except for those who choose to disagree with you.

The aggressive intolerance leveled at the “intolerant” may seem logical (if not honorable) to pop-progressives. But it can feel alienating to folks drowned out by the drumbeat of social-justice warriors.

I’m neither white nor wealthy nor heterosexual; I have no opinion on gender-neutral bathrooms.

Yet I, too, have been repeatedly labeled a racist, sexist, privileged gay-shamer simply for refusing to obey the rules of conventional identity politics. I’ve been told how I’m supposed to act and feel by endlessly “enlightened” strangers deeply convinced that I’m their enemy.

If I feel alienated by this treatment, I can only imagine how Trump’s beloved West Virginia coal miners are coping.

Trump has wisely identified and exploited this sense of isolation — offering a safe space to supporters shut out from increasingly rigid definitions of “acceptable” cultural conversations. Tired of being told what to say and how to think, Trump’s supporters are reclaiming their voice — and publicly committing it to the ballot box.

For the moment, Trump’s supporters don’t include me. But if Clinton wants to win in November, she’d better evolve her message beyond its canned feel-goodness and gender clichés.

Sure, her candidacy is historic — but so is Trump’s. Yes, her political ascent may once have felt unlikely. But it pales in comparison to Trump’s rise from reality-show mogul to Republican chieftain.

Trump is riding a zeitgeist wave he didn’t create. And the unending efforts to divide America into a nation of victims and perpetrators will only perpetuate that surge. Both Trump and Clinton hope to use this to their advantage. Trump, at least for the moment, is winning Round One.
