The 'diploma divide' refers to the growing political polarization in the U.S. based on educational attainment. Voters with college degrees are increasingly aligning with the Democratic Party, while those without degrees are shifting toward the Republican Party. This divide is driving significant shifts in party constituencies and is a key factor in the polarization of American politics, influencing election outcomes and cultural debates.
In the 2024 presidential election, the diploma divide continued to grow, with college-educated voters favoring Kamala Harris and non-college-educated voters supporting Donald Trump. Notably, this divide extended beyond white voters, with significant portions of non-white voters without degrees also moving toward the Republican Party, marking a broader trend across racial groups.
Non-college-educated voters are increasingly aligning with the Republican Party due to cultural and social conservatism. These voters tend to hold more traditional values and are less trusting of institutions like universities and the media. As cultural issues have become central to party politics, these voters are drawn to the Republican Party's emphasis on patriotism and traditional values.
Historically, college-educated voters were more likely to be Republicans, as they were part of the upper strata of society with white-collar jobs. However, this trend reversed in recent decades, with college-educated voters now predominantly aligning with the Democratic Party. This shift reflects broader changes in cultural values and the increasing importance of education in shaping political identity.
Cultural issues are a major driver of the diploma divide. College-educated voters tend to be more socially liberal, supporting progressive values like gender equality and LGBTQ rights, while non-college-educated voters are more socially conservative. This cultural divide has become a central factor in party alignment, with Democrats championing progressive cultural values and Republicans appealing to traditionalism.
The diploma divide significantly affects trust in institutions and expertise. College-educated voters are more likely to trust experts and institutions like universities and the media, while non-college-educated voters are more distrustful. This divide is exacerbated by the perception that experts and institutions are ideologically aligned with the left, fueling a populist backlash against expertise.
The diploma divide has significant implications for future elections. While college-educated voters are more likely to turn out in midterm and local elections, non-college-educated voters still make up the majority of the electorate. Both parties must address the concerns of non-college-educated voters to avoid electoral consequences, as ignoring this group could lead to significant shifts in political power.
The Republican Party has become less supportive of higher education funding and accessibility as the diploma divide has grown. With college-educated voters increasingly aligning with Democrats, Republicans have shifted their focus away from supporting state university systems and scholarships, reflecting a broader partisan divide on education policy.
Some Democrats struggle to connect with non-college-educated voters due to a perceived condescension from educated liberals. Many non-college-educated voters feel looked down upon by those with degrees, leading to resentment and a rejection of Democratic policies. This dynamic is exacerbated by the cultural and social divide between the two groups.
The diploma divide is not unique to the U.S. and reflects broader global trends. Many countries are experiencing similar polarization based on education, with educated voters supporting progressive, globalized policies and non-educated voters favoring populist, nationalist movements. This trend is driven by globalizing, secularizing, and technocratic changes, as well as the backlash against these changes.
One problem with 2016 polling data indicating that Hillary Clinton would win the presidency was the oversampling of people with college and graduate degrees. Today’s Democrats tend to value credentials and degrees, while Republicans tend to champion skeptics who distrust institutions like universities. That’s according to political scientist David Hopkins, who says that the “diploma divide” is a main reason our country is so polarized. We’ll talk to Hopkins about our education divide and its political impacts. His new book, with co-author Matt Grossman, is “Polarized by Degrees.”
