That's the difference between a technocracy and a democracy. If one were to draw a Venn diagram of people who are technically competent (in the field, whatever it may be) and people who are likely to be elected (due to multiple factors, such as interests, "likeability", format of public discorse, the ignorance of the population, etc, etc, etc) one would have no intersection.
