For much of the past two decades, democracies have been fascinated by the political outsider.

Donald Trump promised to run government like a business. Emmanuel Macron built a movement outside France’s established parties. Volodymyr Zelensky came to office as a political newcomer. Andrej Babiš campaigned as the entrepreneur who would manage the Czech state more efficiently than career politicians. Zuzana Čaputová rose from civic activism and environmental law to the presidency, presenting herself as an alternative to Slovakia’s established political class.

Different countries, different traditions, different ideologies. Yet they all reflected a broader belief that politics had become too important to be left to career politicians.

Robert Shrimsley’s recent Financial Times column on Andy Burnham suggests that the pendulum may be swinging back. I think he’s right. But I also think Burnham’s return points to something larger than the rehabilitation of experienced politicians.

Politics itself has changed.

The work has become far more demanding than it was even a decade ago. Artificial intelligence is reshaping research and communications. Campaigns depend on increasingly sophisticated digital infrastructure. Public affairs teams work across regulation, technology and data. Cybersecurity, online communities and platform dynamics are no longer specialist concerns—they are now part of everyday political practice.

As politics has become more complex, it has also become more specialised.

Complexity Creates Professions

Every mature profession follows a familiar path. Medicine relies not only on doctors but on universities, journals, conferences, standards and continuous training. The same is true of law, engineering and finance. Expertise is shared, challenged and improved over time rather than disappearing when individuals move on.

Politics has rarely worked that way.

Knowledge has traditionally remained inside parties, governments and election campaigns. Teams dissolve after polling day. Lessons are lost. The next campaign often starts by solving problems that someone else solved a few years earlier.

That model is becoming increasingly difficult to sustain.

One sign of the change is the emergence of entirely new political specialisms. Twenty years ago, few campaigns employed data scientists, AI specialists or campaign technologists. Today they are becoming standard members of the team. Alongside them, a growing political technology sector is developing tools designed specifically for campaigns, governments and public affairs.

Building the Infrastructure of a Profession

Another sign is the growth of communities where practitioners learn from one another. Campaign managers, digital directors, policy advisers and technology founders increasingly exchange ideas across borders rather than only within parties or national political systems. Politics is slowly building the professional infrastructure that other fields have long taken for granted.

That infrastructure extends beyond technology. It includes conferences, practitioner networks, specialist publications, shared research and communities of practice. These are not side projects. They are the institutions through which professions accumulate knowledge and improve over time.

Modern political success depends less on individual brilliance than on organisational capability. The strongest organisations are usually those that combine different forms of expertise, adapt quickly and continue learning between elections rather than only during them.

The Next Democratic Challenge

For decades we have focused on the quality of political leadership. We have spent far less time thinking about the profession that supports it.

Who trains the next generation of campaign managers? Where do political practitioners develop common standards? How is knowledge preserved instead of being reinvented every election cycle?

These questions rarely make headlines, but they will shape the quality of democratic politics in the years ahead.

Shrimsley is right to observe the return of the political professional. Yet the more important shift is taking place beneath the surface.

Politics is no longer just a vocation or a temporary campaign activity. It is becoming a profession in its own right.

The democracies that recognise that—and invest in the people, institutions and communities that allow political expertise to grow—will be better prepared for the complexity that modern politics now demands.
