That's a very good question for theorists. I'm not one of them.
This is indeed a phenomenon that is not only widespread in developing countries at the moment. However, I think there is a big difference between well-established and less established democracies in terms of their ability to resist change. In some developing countries, where democracy is not necessarily very deeply rooted, it is more difficult.
There are, of course, fears and concerns about some countries such as Hungary and Poland, which are now referred to as non-liberal democracies, that is, countries where we want to continue to hold elections and respect some aspects of democracy, but eliminate some others. We hope that these democracies are well enough established to resist this phenomenon, but this remains to be seen.
