But what if American liberals, while unfortunate in the Electoral College, are luckier than they think in other ways? The fact that populism is flourishing internationally, far from the Electoral College and Fox News, suggests that Trump’s specific faults might actually be propping up American liberalism. If we had a populist president who didn’t alienate so many persuadable voters, who took full advantage of a strong economy, and who had the political cunning displayed by Modi or Benjamin Netanyahu or Viktor Orban, the liberal belief in a hidden left-of-center mandate might be exposed as a fond delusion.

That liberal belief may also misunderstand the real correlation of forces in our politics. We had an example this week on our op-ed podcast, The Argument, where my colleague and co-host David Leonhardt interviewed Pete Buttigieg, the Midwestern mayor running for president with promises to build bridges between the heartland and the coasts. Leonhardt pressed Buttigieg on whether that bridge-building might include compromise on any social issues, and the answer seemed to be “no” — in part because Mayor Pete argued that on abortion and guns and immigration most middle Americans already agree with Democrats, that the liberal position is already the common ground.

The strategic flaw in this reading of the liberal situation is that politics isn’t about casually held opinions on a wide range of topics, but focused prioritization of specifics. As the Democratic data analyst David Shor has noted, you can take a cluster of nine Democratic positions that each poll over 50 percent individually, and find that only 18 percent of Americans agree with all of them. And a single strong, focused disagreement can be enough to turn a voter against liberalism, especially if liberals seem uncompromising on that issue.

A pattern of narrow, issue-by-issue resistance is also what you’d expect in an era where the popular culture is more monolithically left-wing than before. That cultural dominance establishes a broad, shallow left-of-center consensus, which then evaporates when people have some personal reason to reject liberalism, or confront the limits of its case.

None of this needs to spell doom for liberals; it just requires them to prioritize and compromise. If you want to put climate change at the center of liberal politics, for instance, then you’ll keep losing voters in the Rust Belt, just as liberal parties have lost similar voters in Europe and Australia. In which case you would need to reassure some other group, be it suburban evangelicals or libertarians, that you’re willing to compromise on the issues that keep them from voting Democratic.
