PEGGY NOONAN ON DONALD TRUMP:

You know the latest numbers. Quinnipiac University’s poll this week has Mr. Trump at a hefty 28% nationally, up from 20% in July. Public Policy Polling has Mr. Trump leading all Republicans in New Hampshire with 35%. A Monmouth University poll has him at 30% in South Carolina, followed 15 points later by Ben Carson.

Here are some things I think are happening.

One is the deepening estrangement between the elites and the non-elites in America. This is the area in which Trumpism flourishes. We’ll talk about that deeper in.

Second, Mr. Trump’s support is not limited to Republicans, not by any means.

Third, the traditional mediating or guiding institutions within the Republican universe—its establishment, respected voices in conservative media, sober-minded state party officials—have little to no impact on Mr. Trump’s rise. Some say voices of authority should stand up to oppose him, which will lower his standing. But Republican powers don’t have that kind of juice anymore. Mr. Trump’s supporters aren’t just bucking a party, they’re bucking everything around, within and connected to it.

Since Mr. Trump announced I’ve worked or traveled in, among other places, Southern California, Connecticut, Georgia, Virginia, New Jersey and New York’s Long Island. In all places I just talked to people. My biggest sense is that political professionals are going to have to rethink “the base,” reimagine it when they see it in their minds.

I’ve written before about an acquaintance—late 60s, northern Georgia, lives on Social Security, voted Obama in ’08, not partisan, watches Fox News, hates Wall Street and “the GOP establishment.” She continues to be so ardent for Mr. Trump that she not only watched his speech in Mobile, Ala., on live TV, she watched while excitedly texting with family members—middle-class, white, independent-minded—who were in the audience cheering. Is that “the Republican base”? I guess maybe it is, because she texted me Wednesday to say she’d just registered Republican. I asked if she’d ever been one before. Reply: “No, never!!!”

Something is going on, some tectonic plates are moving in interesting ways. My friend Cesar works the deli counter at my neighborhood grocery store. He is Dominican, an immigrant, early 50s, and listens most mornings to a local Hispanic radio station, La Mega, on 97.9 FM. Their morning show is the popular “El Vacilón de la Mañana,” and after the first GOP debate, Cesar told me, they opened the lines to call-ins, asking listeners (mostly Puerto Rican, Dominican, Mexican) for their impressions. More than half called in to say they were for Mr. Trump. Their praise, Cesar told me a few weeks ago, dumbfounded the hosts. I later spoke to one of them, who identified himself as D.J. New Era. He backed Cesar’s story. “We were very surprised,” at the Trump support, he said. Why? “It’s a Latin-based market!”

“He’s the man,” Cesar said of Mr. Trump. This week I went by and Cesar told me that after Mr. Trump threw Univision’s well-known anchor and immigration activist, Jorge Ramos, out of an Iowa news conference on Tuesday evening, the “El Vacilón” hosts again threw open the phone lines the following morning and were again surprised that the majority of callers backed not Mr. Ramos but Mr. Trump. Cesar, who I should probably note sees me, I sense, as a very nice establishment person who needs to get with the new reality, was delighted.

Well, Peggy, he’s got you pretty well figured out. And yes, America has the worst political class in its history, average people are figuring it out, and — finally — the political class is beginning to figure out that average people are figuring it out.

Does this mean that Trump should be President? No, but it means someone capable of absorbing, and putting into practice, the things that Trump is making clear should be.
