Well, algebra15, the fact that you're looking for a scapegoat, rather than a "leader" who can manage the society in a more efficient manner (after all, that is what, ostensibly, people are trying to do when they go and vote in national elections) and satisfying larger proportion of the populace, is indicative that you're expecting them to be a failure or/and not satisfy your needs anyway. So, from that point of view, given neither would satisfy you, in this case you're simply going for the "looks", rather than "substance".
Would it make a differece then if you were "ruled" by a British monarch, a Chinese com-party leader, the French President, or the Happy Council of the Hippies (all theoretical possibilities)? It might just be possible the machine, via simple, unemotional approach and statistical analysis, just might make decisions which are there for benefitting the majority, rather than itself... is it really that bad? (Though, the dubious questions of what statistics are used, who supplies them, and manipulation of the machine via the data it is fed are ignored for teh time being.)
