The gulf between the party identification of white voters with college degrees and those without is growing rapidly. Trump is widening it.

One of the most striking patterns in yesterday’s election was years in the making: a major partisan divide between white voters with a college degree and those without one. According to exit polls, 61 percent of non-college-educated white voters cast their ballots for Republicans while just 45 percent of college-educated white voters did so. Meanwhile 53 percent of college-educated white voters cast their votes for Democrats compared with 37 percent of those without a degree. The diploma divide, as it’s often called, is not occurring across the electorate; it is primarily a phenomenon among white voters. It’s an unprecedented divide, and is in fact a complete departure from the diploma divide of the past. Non-college-educated white voters used to solidly belong to Democrats, and college-educated white voters to Republicans. Several events over the past six decades have caused these allegiances to switch, the most recent being the candidacy, election, and presidency of Donald Trump.

The gap is likely to be one of the most powerful forces shaping American politics for decades to come. The Democratic and Republican Parties looked a lot different in 1952, when the American National Election Studies—surveys of voters conducted before and after presidential elections—were in their infancy. The Republicans, to some extent, were still regarded as the party of Lincoln, even though they had shifted their focus to courting southern white voters, causing black people to leave the party. Meanwhile, the Democrats were the party of a coalition that pushed for social services—the party of the New Deal. There were far fewer college-educated Americans at the time, but the white Americans who did have degrees tended to vote Republican, and those who didn't sided with the Democrats by a significant margin. This split was relatively stable for decades and then, steadily, it began to change. “The shift in whites without a college degree away from the Democratic Party begins as the Democratic Party becomes identified as the party of civil rights,” starting in the 1960s, Robert P. Jones, the CEO of the Public Religion Research Institute, told me. Disaffected white southern Democrats, in particular, fled in droves.

Party realignment doesn't happen overnight. Just because some voters swing across the aisle in one election doesn't mean they’ll quit the party they've identified with their entire lives. Still, strong support for the Democrats among whites without a college degree, borne out of economic incentives—and racial resentment—began to wane. In their book, The Rise of Southern Republicans, the scholars Merle Black and Earl Black call this shift the “Great White Switch.” From the mid-1990s to 2008, the diploma divide was small, if not negligible. Even though the Democrats had become the party of civil rights and a broad, multicultural coalition, they were also still the party of unions, which were largely made up of non-degree-holding whites. Therefore, white people with and without college degrees were equally as likely to be Democrats or Republicans. But in 2008, the election of Barack Obama, a black man, signaled that the Democrats were becoming the party of progressive racial politics. “Obama’s presidency simplifies the politics of race,” Michael Tesler, an associate professor of political science at UC Irvine, says. “If you were a low-educated white, you were much more likely to know about the partisan differences on race [after Obama] than you were before.” That change didn’t show up in the party-affiliation data right away, but that’s common, Tesler says. It often takes more than one election for people to switch their party identification. But by 2012, white voters without a college degree were distinctly more likely to vote Republican than those with college degrees.

A Marist poll in October of this year found that 55 percent of non-college-educated white voters approved of the job Trump was doing, compared with just 39 percent of college-educated white voters. When Supreme Court Justice Brett Kavanaugh squeaked through a Senate confirmation hearing with a sexual assault allegation in tow, 54 percent of non-college-educated white voters supported him, compared with 38 percent who had gone to college. And the partisan diploma divide held steady last night, reflecting a divide in values between those with degrees and those without. There’s a question that splits Americans neatly in two. Every year, on its American Values Survey, the Public Religion Research Institute asks Americans whether they “think American culture and way of life has mostly changed for the better, or has it mostly changed for the worse,” since the 1950s. Fifty percent of Americans say that it’s gotten better in this year’s poll, and 47 percent say that it has gotten worse. But for white voters, the answer to that question is split by education level. Fifty-eight percent of college-educated whites this year say that America has gotten better since 1950, while 57 percent of non-college-educated whites say that it’s gotten worse. When President Trump says “Make America great again,” the again is instructive. He’s capitalizing on the nostalgia that non-college-educated white voters have for America’s past. “That harkening back to a supposed golden age where things were better has a really, really strong appeal for whites without a college degree,” Jones said.

That nostalgia, however, is for a time when black Americans and other minority groups had significantly fewer civil rights. And a Republican rhetoric that centers a longing for an era of white prosperity, rife with racist violence against black people, is why it’s impossible to understand the diploma divide without accounting for racial resentment. Needless to say, black Americans and other minority groups aren’t as keen on returning to the past. Read: The nationalist’s delusion When researchers control for voter attitudes on race in addition to white voters’ education level, Tesler says, the diploma divide disappears. No other factor, he says, explains the education gap as well—not economic anxiety, ideology, income, or gender. David N. Smith, a professor at the University of Kansas, came to a similar conclusion when he and Eric Hanley took a dive into the 2016 American National Election Survey. They found that demographic data such as education are important predictors of which party someone votes for. But “when you bring the attitudes variables into account as well, what emerges is that attitudes loom even larger than demographics,” he told me. Here’s how he put it: If you look at white people who voted for Trump—both those with college degrees and those without—and identify everybody with a high level of resentment toward minorities, women, and Muslims, as well as those who want an arrogant, assertive leader, there’s almost no one left. The vast majority of Trump voters share those sentiments, the researchers found, regardless of education level.

The GOP has come around to Trump. As my colleague McKay Coppins wrote, “Trump’s conquest of the Republican Party is complete, and the former ‘fringe’ has become so thoroughly intertwined with the ‘establishment’ that the two are virtually indistinguishable.” The growing diploma divide is less a result of non-college-educated white voters becoming Republicans, and more of college-educated white voters finding that they can’t fully support the party anymore. “What's happened since 2016 is that the low-educated whites have kind of plateaued in their support for the Republicans,” Tesler says. “But you've seen this trend increase [of] high-educated whites [moving] towards the Democrats.” Smith told me that from 2015 to 2017, the Weidenbaum Center at Washington University in St. Louis conducted a monthly panel survey—where the same statistically significant number of people are interviewed each month—that cataloged Republican attitudes toward Republican candidates. Over time, those who supported Ted Cruz, who called Trump a “sniveling coward” during the campaign, and those who supported Marco Rubio, who called him a “con man,” tended to come around to Trump. But the voters that stand out, Smith said, are those who initially supported John Kasich. “They, in many instances, agree with Trump on policy issues, but the best data indicates that they are uncomfortable with him personally,” he said. “There are key aspects of his rhetorical style, of his governing style, that they don't like.”
