People who think one good man (like say, Ron Paul) can turn a civilization around singlehandedly when it has reached the end of it's life do not have sufficient understanding of the problem.
Civilizations don't rise or fall because of one good or bad leader. Civilizations are simply an expression of the genetics of the people who live in them. Casting about for some superman to save you near the end is futile - superman could not save you at this stage.
Marcus Aurelius would have to be one of the best damn men that ever walked the planet in the secular arena, full of virtue and steeped in good judgement, excellent character, honesty and integrity. He took the job of emperor of Rome at a time it was such a crappy job no decent human being would want to do it. He spent his entire life trying to recapture and secure the borders of Rome until the day he died, attempting to restore some civil order and practice sound monetary policy.
It didn't work. When Aurelius died the Roman Empire went right back to the greased sluice downhill.
This is why I think people hoping for a Ron Paul victory underestimate the size of the problem. It's too much for any one man to handle. Even if Ron Paul got in and had two terms, he would have to fight every politician in the country and every single reform he tried to install would be resisted at every turn. Sooner or later he'd be out of office and the country would return to the dismal tide it tracks now.
There are exceptional men and great leaders born in this world, I hope sent by God to test men's judgement and see if they have the sense to elect them.
In most cases they don't. In fact, in declining civilizations it is the good men who stand the least chance of changing anything. This is why they tend to retreat to their own private gardens.
UPDATE : Amerikwa needs independent observers to give their elections any legitimacy.
