Neither Hitler nor Trump campaign on specific policies, beyond a few slogans. Instead, both promise a new vision of leadership. They portray the existing political systems as fundamentally corrupt, incompetent, and, most importantly, unable to generate decisive action in the face of pressing problems.
Both use their personal biographies—or rather, the highly edited accounts of their personal biographies they present to the media—to conjure up a new style of politics, which is based neither on expertise nor on detailed policy proposals. Instead—they suggest—their own personal 'struggle' shaped them into—supposedly—authentic leaders, capable of overcoming adversity through sheer force of character. In this scenario, democracy has less to do with representative institutions than with a leader who is intuitively 'in tune' with the sentiments of the people.
Like Hitler, Trump is capitalizing on a longing for charismatic leadership, to which even highly developed Western democracies seem very susceptible when democratic structures fail to deliver all the desired outcomes. No Western democracy currently faces problems on the scale of those Germany grappled with before 1933. And yet, there is a very real sense amongst a large part of the population that they have not been on the "winning side" for a long time.
The gap between rich and poor is getting wider, and in the process, the classical attributes of political leadership—education, expertise, eloquent speeches—have come to be seen not as problem-solving strategies, but as the identity markers of a social elite who are looking after their own interests only.
