Segnosaur: I have to disagree with your last statement. The most educated voters can be complete idiots when it comes time to cast their ballots. Sometimes all it takes is believing that they're smarter than the sheep in the neighboring pasture.
As an example: Germany, in the 1920s and early 1930s (the Weimar Republic, prior to HItler's chancellery) had a very educated population. Germans in the runup to the Hitler era were also very active, politically; even more active than they are today, as far as joining political associations and being politically involved. Their high level of education and political involvement did not stop the rise of the NSDAP, did it?
At the end of the day, all of us, regardless of our level of intelligence, education and political involvement---or even which country they live and vote in---are in danger of being led to the slaughter by wily political leaders and their publicity machines.
