This Christian Science Monitor article details the signs that Jean-Bertrand Aristide was doomed to failure as President of Haiti. The CSM notes:

How a man hailed as a potential Nelson Mandela for his impoverished and oppressed nation of 8 million could fall so far appears to be as much a tale of wishful thinking by desperate Haitians and the international community that backed him, say experts, as it was a tale of the old clichÈ that “absolute power corrupts absolutely.”
Aristide was given that rarest of political gifts – a second chance. But, reinstalled in the presidency in October 1994 by a multinational military force, he used his resurrection to perfect an autocratic style, say even those close to him who were interviewed for this story.
Today, having infuriated, humiliated, and – some allege, killed – any once-devoted followers who crossed him, Aristide has few political allies left. Even his strongest credential – his election to a second term in 2000 – counts little as rebels gobble up territory and threaten to take the capital.
Languishing in that familiar pre-coup limbo that is a trademark of modern Haitian presidencies, Aristide is a symbol of a political culture that has been bankrupt nearly since it began as a slave revolt 200-plus years ago. . .
