I am not sure why you are being downvoted, because IMHO you are correct.

If Trump was an isolated incident, sure, but he is not. In Europe the far-right and far-left parties are rising in many countries and the traditional parties are crumbling.

I think there is a serious lack of trust in the institutions and in the politicians that is spreading around the world at a quick pace and many people are just fed up with the status-quo that has been in place since the fall of the USSR.

People want change, not small marginal tinkering on the edges, they want to see that things move decisively in one way or the other and they are not afraid to flip the table and see what happens.
