I bet superdelegates are more likely to know the answers to those questions, and guess what, their vote counts for more. I thought you hated the DNC
I'm not a fan of the crowds' wisdom either but if i were concerned about the influence of the uneducated masses on my future, i'd do whatever i could do to have/build a more educated society, instead of removing the uneducated from voting. I would, among other things, willfully pay more taxes to enable people to have easier access to education. To me, that's a sustainable solution.
As for the bold part, of course that's true. All an uneducated individual is doing is voting. I, however, don't think that an elitist minority would pick a better candidate among say Sanders, Clinton, Trump and Cruz than would the less educated majority, because i firmly believe that the root of poor and destructive decisions at the highest level is greed, and your knowledge of where Iraq is on the map won't help you spot that in a candidate.
I don't think anybody pretends to know that. Quite on the contrary, it's actually in the system you are talking about (and i don't honestly think Sowell implied what you said) that a group of people decide what's best for millions of people. In the current system, you pick the one candidate you think is a better option for yourself.
I was obviously joking but if you strongly feel that an uneducated bunch is having a powerful say in your and your country's future (with which i agree), how would refusing to vote help mitigate that influence?
