I can't remember the title, but there was this short (sci-fi) story about some utopian planet where the protagonist went. after being there for a while, he was asked to become the president of the planet, and he agreed to it. so then when the old president put the protagonist in charge, the old presidents head exploded due to explosives. see, anyone on the planet that was unhappy with his rule could just go press a button... direct democracy through explosives, I guess. it might have been called "ticket to utopia" or something along those lines.
oh, and the link doesn't want to work, so I just guessed what the article was about.
