The fatal flaw of democracy is that the vote of a fool has the same weight as the vote of the informed. Since there are more foolish people than informed people, the result of democracy is almost always foolishness.
The only way a democracy might work is when the informed people outnumber the fools. And that usually happen after a bloody struggle. Lets face it, in a country where people have to Elect between Obama the Liar and Flip-Flop Romney, the result will not even be foolish, but evil.
When one chooses the lesser of two evils. One is still choosing evil.
Either you're an early riser, or you're writing from the east side of the Atlantic: so your ignorance of how, why and for whom this democratic republic was formed is forgivable. The fact that it, like most other forms of populist government today, has been bought out and corrupted by multinational money interests has nothing to do with the minds, vision and desires of those who created it.
