Voters rarely make decisions as to who is in power; they are forced to select from a small group of candidates which have come so far already, and then a committee choses which candidate is best and makes them compete for election. I do not think that a system based on the agency of people rather than the agency of ideas is a good system.
Sometimes the voters don't actually get their say; a national organisation overrides their will. Sometimes the democratic pathways are blocked by media misinformation. These are problems of the situation in which democracy is placed, and they have been recognised at least as far back as Marcuse wrote in the 1960s. The problem is less to do with whether people get candidates in power, it's more to do with how well people are informed as to the true nature of their reality. It may sound as though I'm saying "people don't know what they want", but my intention is to advance to the super-democratic status of "people must obtain the information they need".
Marcuse puts it better than I ever could:
>The liberating force of democracy was the chance it gave to effective dissent, on the individual as well as social scale, its openness to qualitatively different forms of government, of culture, education, work--of the human existence in general. The toleration of free discussion and the equal right of opposites was to define and clarify the different forms of dissent: their direction, content, prospect. But with the concentration of economic and political power and the integration of opposites in a society which uses technology as an instrument of domination, effective dissent is blocked where it could freely emerge; in the formation of opinion, in information and communication, in speech and assembly. Under the rule of monopolistic media--themselves the mere instruments of economic and political power--a mentality is created for which right and wrong, true and false are predefined wherever they affect the vital interests of the society.
