Well the answer is obvious.  It's Bill Clinton.  Though he has been out of office for almost a decade the man is still a powerhouse on the Global scene.  That he has taken on the special envoy position with the U.N., especially considering his less than pleasant encounters with Haitian restoration during his Presidency speaks to Clinton's commitment.  I'd wager he feels a sense of responsibility toward the situation in Haiti beginning with U.S. policy in the 1990's and has been itching to take a crack at the problems that have spawned from that time.  With that much commitment and all the Clinton clout (around the world with donors in particular) it would seem a great opportunity is available to bring some meaningful change and development for the people of a country ravaged by poverty, lawlessness and corruption not to mention the devastating effects of natural disasters in recent years.  Furthermore, avoiding any puns, the timing could not be better for Clinton to get involved.  Big money has just been pledged in aid for Haiti from the U.S. and the upcoming elections there are wide open with some visionaries running for high offices.  We saw what Bill Clinton was able to do economically for this country against some tough odds with a high rate of success.  He was not able to see his hopes for Haiti achieved at that time but with his new position and the new circumstances I would not be surprised to see peace and prosperity in Haiti's near future.
