99% of people are idiots... so you would be in the 1%, I guess?
I guess I'm a bit more hopeful, because most of the people I know, even ones whose judgement I would never trust, aren't idiots - they are stressed, overworked, bombarded with propaganda (political and commercial) and their educations have been structured (not necessarily intentionally, though it certainly benefits the powerful) to produce obedient workers and "consumers", not free-thinking, critically-minded citizens.
Moreover, aside from those people who are driven to make politics or activism the central part of their lives (which, given work and stress, etc., simply isn't possible for many even if the desire is theere) for most people the sole opportunity to engage directly in politics comes one day every couple years. And the lead up to that day rarely includes much open-ended discussion; rather its shaped by intense propoganda carpet bombing.
There are lots of other factors; I think that one is automobile-oriented culture, which for all its possible benefits, has hurt democracy as well. For most people, casual daily contact with strangers is non-existent; when "community" becomes an abstract concept rather than a lived-in, concrete reality, how realistic is it to expect the average person to feel, at a deep level, a need to think or care about things outside their family, friends and job? Television, aside from its propaganda uses, produces similar effects (interfacing with reality and the community through media rather than concrete, face-to-face experiences).
The bottom line is that "most people" are perfectly capable of making informed and intelligent decisions about important issues, if they have time to think about them, the opportunity to discuss them, and have receieved (formally or just through life experience) an education that includes some real critical thinking skills
OK, rant off.
One final thing - the parent says "Representative to cast votes: congressman." in response to the previous post's suggestion of designated representatives in a direct democracy system. I read that suggestion very differently:
In place of (or in addition to) officials elected to a congress, one could have people you knew and trusted (your very politically knowledgeable friend, for example) act as proxies in a direct democracy system. For example, most of my friends don't really care about copyright law (except to the degree that they think RIAA lawsuits are total BS), but they know I'm interested and reasonably knowledgeable about it. If direct democracy meant people voted on every issue, you could conceive a system where my friends could grant me proxy power on copyright issues, subject to their review of my decisions.
I can see some dangers (e.g., an abusive husband demanding his wife's vote), although these dangers would probably be the same as in any absentee voting system. This seems like a pretty interesting idea.
