The Rise of Polarised Politics

Political polarisation has become a global trend in the past 10–15 years, particularly in democracies. The local elections in the U.K. in early May have clearly shown that the political landscape in Britain is now getting more polarised as well, following in the footsteps of for example Germany, Spain and France to name but a few other European nations.

On one hand this may be desirable, as more political parties cover the ever more nuanced opinions of voters. But on the other hand this also leads to the votes being split between ever more groups, with none of them being able to muster enough votes to form a government on their own. This in turn leads to more or less vulnerable and unstable coalitions which may not achieve much over a parliamentary term.

Years ago political affiliations were meaningful: The working classes would vote to the left. Bosses, bankers and consultants would lean to the centre-right or the outright right of the political spectrum. Not anymore. Now voters may side on some issues such as workers rights with the left,while being opposed to immigration, a typical theme of the right. Many people nowadays give their vote to politicians who most closely represent their own worldview. This is definitely one of the reasons which explains the success of populist parties such as Reform in the U.K, RN in France and AfD in Germany.

Another aspect is age: Younger voters tend to be more liberal and vote accordingly, whereas older people, who often also are likely to be more financially secure, will be more conservative. Often this is helped by the fact that the elderly will have retired and hence will be less concerned by workers rights but more by immigration which is supposedly draining state resources such as social- and healthcare which they are increasing depending on.

Europe has become accustomed to polarised politics, but could America be next? There is an argument—quietly growing louder—that the US is not “next” but rather ahead of Europe in the polarisation curve.

Unlike Europe’s multi-party ecosystems, the US operates within a rigid two-party structure. This creates a zero-sum dynamic: politics becomes less about coalition and more about conquest.
Where European fragmentation diffuses disagreement across a wider spectrum, the American system concentrates it into two camps. The result is not merely disagreement, but identity-level antagonism. Compromise, in such a structure, is not seen as pragmatism—it is seen as betrayal

The American media landscape—particularly cable news and algorithm-driven platforms—has evolved into parallel universes. Citizens increasingly inhabit informational bubbles where opposing views are not debated but dismissed. Europe, on the other hand, and for all its tensions, still retains relatively strong public broadcasters and cross-cutting media frameworks. The US, by contrast, has perfected the art of segmented reality.

A key feature of advanced polarisation is the shift from policy disagreements to cultural identity battles. Issues such as migration, race, and social norms increasingly define political allegiance. This mirrors trends in Europe—Brexit being the most obvious example—but in the US the intensity is arguably higher, with politics permeating everyday social interactions, corporate decisions, and even personal identity.

Polarisation feeds on declining trust in elections, courts, media, and government. Once institutions are perceived as partisan actors, every decision reinforces suspicion. This pattern has been observable in both Europe and the US, but the American system with its highly visible and politicised institutions may be particularly vulnerable. And yet, the inevitability narrative deserves scrutiny. There are structural and cultural differences that could slow or even partially reverse the trend.

The US federal system allows states to operate as semi-autonomous entities. This decentralisation can absorb conflict: policy disagreements do not always need to be resolved at the national level. Europe has something similar in the EU framework, but it is less cohesive and often slower to act. In the US, federalism can function as a form of conflict management rather than conflict escalation. Polarisation Is high but Also cyclical. History suggests that American political life moves in waves. Periods of intense division have been followed by phases of relative consensus. In this context the current moment feels uniquely acute, but then so did earlier ones. The US has a track record of recalibrating, albeit unevenly.

Economic stability—or at least resilience—can moderate extreme political behaviour. While inequality and cost-of-living pressures persist, the US economy clearly demonstrates a capacity for growth and adaptation. Europe’s more fragmented economic landscape sometimes amplifies political discontent, particularly when national governments have limited fiscal room to manoeuvre.

But polarisation can nowadays even manifest itself within political parties: The resignation of Sir Keir Starmer, the British Prime Minister shows how fractured the Labour Party in itself is. Sir Keir, a moderate, ultimately had to pander to the left wing to try to hold the party together. In vain, as it turns out. His successor, be that Andy Burnham, former Mayor of Manchester and a soft leftist or someone else will find it hard to rally rebellious Labour members of parliament, let alone increasingly fractious voters.

In many developed nations it is hard nowadays to imagine a political landscape that is any less polarised. This will not make political decision-making any easier. We all better get used to a growing number of half-hearted alliances and unsatisfactory compromises. These in turn might well lead to more dissatisfaction among the electorate.
