Once upon a time, a good many years ago, there was a science-fiction story about how that society selected a president of the United States.
The story is decades old, written before computers were ordinary, certainly before there was the Internet. I cannot remember whether it might have been a short story as part of a collection, or maybe half of one of those paperbacks that had a "front cover" on both sides.
Somehow (computers, maybe - or maybe the powers that be) chose a single individual who would cast one vote, and the person he selected would become the new president.
Sorry for the fuzzy details; that's the best I remember it. Anybody else remember the story and can supply the name or author?
