A very long time ago I read a short sci-fi book about a future in which all political and social decisions were based on electronic votes from the populace. There was some element of corruption in the process. I think this was a story by Lem, but I'm not sure. It seems like a story he would write. I've ransacked the Lem web site for a clue, but no luck. Any clues about if it was Lem, or someone else entirely?
