Two relevant quotes from "Hitchhiker's Guide to the Galaxy"
The leaders are lizards. The people hate the lizards and the lizards rule the people.
Odd, said Arthur, I thought you said it was a democracy.
I did, said Ford. It is.
So, said Arthur, hoping he wasnt sounding ridiculously obtuse, why dont people get rid of the lizards?
It honestly doesnt occur to them, said Ford. Theyve all got the vote, so they all pretty much assume that the government theyve voted in more or less approximates to the government they want.
You mean they actually vote for the lizards?
Oh yes, said Ford with a shrug, of course.
But, said Arthur, going for the big one again, why?
Because if they didnt vote for a lizard, said Ford, the wrong lizard might get in. Got any gin?
― Douglas Adams, So Long, and Thanks for All the Fish
The major problem one of the major problems, for there are several one of the many major problems with governing people is that of whom you get to do it; or rather of who manages to get people to let them do it to them.
To summarise: it is a well known fact that those people who most want to rule people are, ipso facto, those least suited to do it. To summarise the summary: anyone who is capable of getting themselves made President should on no account be allowed to do the job. To summarise the summary of the summary: people are a problem.
