def totalitarian::"relating to a system of government that is centralized and dictatorial and requires complete subservience to the state" and let me quote King Louis XIV, "L'etat c'est moi" (I am the state)

When people make the comparison they are implying Mr Trump would like to have a centralized state with complete dictatorial control over that state ... and remember he requires complete subservience to the state ... for he is the state.

If the comparison eludes one .... look with objectivity
