It is often identified as a problem for parties of that ilk that they fall under the thumb of a single powerful leader with little time for party democracy and expects all internal matters to be little more than rubber stamping their own agenda. The afd kind of reflects what happens if this figure isn't present, because these central figures, even the ones with absolutely no interest in moderation like Geert Wilders, are constantly purging their parties of non aligned figures and tendencies. The AfD has no Farage or Le Pen with universal support amongst the memberbase, just a bunch of ephemeral political hacks.
Even Fidesz and Law And Justice have Orban and Kaczynski who mostly have support amongst their member bases but loathed across the liberal opposition but they are never going to moderate those 2 parties. Just look at their leaders 2 frequent feuds with the European Union. And orban's pandemic powers make him look like a more democratically version of Putin and Lukashenko
