His argument can be used on Americans as well, on more than one occasion in history. :)
If he is indeed a historian, there are surely many omissions in his long term memory.
As I said before, in the primaries, the candidates need to say what the card carrying members want to hear, even if it is stupid. And as a result, the moderates get to choose between left and far right, there is not a center candidate. Every so many years, people get annoyed with the incumbent party, so the other candidate gets chosen pseudo automatically, regardless of the fact that he is far left or far right.
As a result, you get a race to the bottom in which the moderates always lose.
