My readers must have a pretty good idea of it. Incompetent party bosses are re-elected forever and parties cannot be rejuvenated. In this system sovereignty belongs to the party bosses, not to the people. Obviously, that is unconstitutional. It is unlawful to criticize the government.
Criticism is equated to insult and people get prison terms.
Parties are financed by the government, not by their members. The worse aspect of it is that Partycracy cannot be changed democratically, because the partycrats would not want to give up their sovereignty. I believe that, most of the ills of the country are direct consequences of this bad election system. The government of Turkey is presently run by an old sickly prime minister, who is only a few days a week on his job. Some of the things they do is downright pathetic.
