“In order for democracy to work, competing parties must accept that they can lose elections, and that it’s okay. But when partisans see their political opposition not just as the opposition, but as a genuine threat to the well-being of the nation, support for democratic norms fades because “winning” becomes everything. Politics, in turn, collapses into an all-out war of “us against them,” a kind of “pernicious polarization” that appears over and over again in democratic collapses, and bears a striking similarity to what’s currently happening in the U.S.
There’s no shortage of plausible explanations for why U.S. politics has become so polarized, but many of these theories describe impossible-to-reverse trends that have played out across developed democracies, like the rise of social media and the increased political salience of globalization, immigration and urban-rural cultural divides. All of these trends are important contributors, for sure. But if they alone are driving illiberalism and hyper-partisanship in the U.S., then the problem should be consistent across all western democracies. But it isn’t.
What’s happening in the U.S. is distinct in four respects.
First, the animosity that people feel toward opposing parties relative to their own (what’s known as affective polarization in political science) has grown considerably over the last four decades. According to a June 2020 paper from economists Levi Boxell, Matthew Gentzkow and Jesse M. Shapiro, the increase in affective polarization in the U.S. is the greatest compared to that of eight other OECD countries over the same time period.
Second, the change in how Americans feel about their party and other parties has been driven by a dramatic decrease in positive feelings toward the opposing party. In most (though not all) of the nine democracies, voters have become a little less enthusiastic about their own parties. But only in the U.S. have partisans turned decidedly against the other party.”

” Third, more so than in other countries, Americans report feeling isolated from their own party. When asked to identify both themselves and their favored party on an 11-point scale in a 2012 survey, Americans identified themselves as, on average, 1.3 units away from the party that comes closest to espousing their beliefs”
…
“This gap is the highest difference Rodden found among respondents in comparable democracies. This isolation matters, too, because it means that parties can’t count on enthusiasm from their own voters — instead, they must demonize the political opposition in order to mobilize voters.
Fourth, and perhaps most significant, in the U.S., one party has become a major illiberal outlier: The Republican Party. Scholars at the V-Dem Institute at the University of Gothenburg in Sweden have been monitoring and evaluating political parties around the world. And one big area of study for them is liberalism and illiberalism, or a party’s commitment (or lack thereof) to democratic norms prior to elections. And as the chart below shows, of conservative, right-leaning parties across the globe, the Republican Party has more in common with the dangerously authoritarian parties in Hungary and Turkey than it does with conservative parties in the U.K. or Germany.
The U.S. is truly exceptional in just how polarized its politics have become, but it’s not alone. People in countries with majoritarian(ish) democracies, or two very dominant parties dominating its politics like in the U.S. — think Canada, Britain, Australia — have displayed more unfavorable feelings toward the political opposition.
In fact, in a new book, “American Affective Polarization in Comparative Perspective,” another team of scholars, Noam Gidron, James Adams and Will Horne, shows that citizens in majoritarian democracies with less proportional representation dislike both their own parties and opposing parties more than citizens in multiparty democracies with more proportional representation.”
…
“there is also something particular about what’s happening in the U.S., even compared to other majoritarian(ish) democracies. For example, the major parties on the right in Canada and Australia have not become as illiberal as their American counterpart.”
…
“While it is both easy and appropriate to criticize Trump and fellow Republicans for their anti-democratic descent in service of the “Big Lie,” it takes more work to appreciate how the structure of the party system itself laid the groundwork for the former president’s politics of loathing and fear. A politics defined by hatred of political opponents is a politics ripe for hateful illiberalism.
The new scholarship on comparative polarization is crucial in understanding this dynamic. In one sense, it offers a very depressing view: Given the current binary structure of American party politics, this conflict is mostly locked in. No level of social media regulation or media literacy or exhortation to civility is going to make much of a difference. But it also offers a kind of master key: If the structure of a party system is as crucial as these studies suggest it is, then the solution is obvious: The U.S. may want to change its voting system to become more proportional.”
