CNN recently published a surprisingly starkly worded opinion piece titled Stupid voters enable broken government. The gist of the article is that we have governments we elect, and therefore governments we deserve.

But do we, really?

A commenter points out the following:
Most eligible voters don't even vote. Only 37% did in the 2010 election. That means it only takes 18.87% of all eligible voters to get elected. And that means a candidate must pander to the bat shit crazies...because the batshit crazies are definitely voting.

It's very likely the other 63% of voters don't show up to the polls because they don't think the candidates represent their views. This works out to a feedback effect since if they did show up, their opinions would carry weight and the candidates would reflect their views.
I've spent a fair amount of time contemplating the faults of democracy, but its salvation might be much more straightforward than I thought.

Edit: Wikipedia has a list of countries with compulsory voting. Out of countries that have it, 12 countries are listed as enforcing it. Prominent among these are: Argentina, Australia, Brazil, Chile, Ecuador, France, Peru, Singapore, Uruguay. Most of these countries don't seem to be faring too badly, but they seem to vary widely nevertheless.
