The inherent nature of government guarantees sociopaths and narcissists to rise to the top because they have the most motivation and the most to gain from it.
A guy who thinks you can't rely or expect the government to take care of you is a guy who doesn't want to get elected and nobody wants to elect him.
People want the government to solve all the problems and provide all the services and be told what they want to hear and the sociopaths are right there to provide those promises
