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.
It is possible for an educated person to make a foolish decision when voting. But I do think it is less likely.
Compare 2 voters: One with a reasonable amount of education, who gets their information from reputable sources. They know a little about science, the humanities, etc. The other a high-school dropout who gets all their information from Fox News and OAN and has Infowars bookmarked on their browser.
Who would you trust more to pick a political leader?
By the way, when I say "educated" I don't just mean "do they have a university/college degree"... I also mean in part what type of information sources do they access on a regular basis. Canada doesn't have an equivalent of "fox news", the christian right (a major source of misinformation) isn't as influential, and our 'talk radio' doesn't seem to have the same right-wing bent.
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?
Not really sure if the Weimer republic is a useful example for anything for several reasons. (They didn't have a long history of democracy at that point, hitler never received a majority, the options in that time frame were limited, the success of hitler at the time says nothing about whether those with the most education supported him or some alternative, etc.)
