It isn't so much about totalitarian regime as about hordes/tribes/clans nature of Kazakh society.Actually totalitarianism stems from there.

In the Khanate of Kazakhs all the power was concentrated in the khan's hands. The khan was a symbol of the Centre of the Society and Cosmos, he guaranteed the stability in the State and Nature.
In the post-Mongolian steppe states there existed a tradition, according to which the khan was elected from Chingiz-khan's descendants (Chingizids). This days khan is called president.
There are also middle and new hordes. The military/security structure reflects that order.
Both Nazarbaev and Tokaev hordes are Chingizids.
