Stop voting for the lizards

After a long, heart-stopping moment of internal crashes and grumbles of rending machinery, there marched from it, down the ramp, an immense silver robot, a hundred feet tall.
It held up a hand.
“I come in peace,” it said, adding after a long moment of further grinding, “take me to your Lizard.”
Ford Prefect, of course, had an explanation for this.
“It comes from a very ancient democracy, you see…”
“You mean, it comes from a world of lizards?”
“No, nothing so simple. Nothing anything like to straightforward. On its world, the people are people. 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 wasn’t sounding ridiculously obtuse, “why don’t the people get rid of the lizards?”
“It honestly doesn’t occur to them,” said Ford. “They’ve all got the vote, so they all pretty much assume that the government they’ve 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 didn’t vote for a lizard, the wrong lizard might get in,” said Ford. “Some people say that the lizards are the best thing that ever happened to them. They’re completely wrong of course, completely and utterly wrong, but someone’s got to say it.”
“But that’s terrible,” said Arthur.
