Results in Haiti show that musician Michel "Sweet Micky" Martelly has won the runoff for the presidential election. Martelly defeated former first lady Mirlande Manigat. Running on a campaign of change, the outsider garnered 67 percent of the vote, according to the Provisional Electoral Council, while Manigat only managed just over 30 percent. However, observers say turnout was low and Martelly has a slew of challenges facing him once he is in office.

Former Haitian dictator Jean-Claude Duvalier, known as Baby Doc, returned to Haiti on Sunday after spending nearly 25 years in exile in France. Duvalier became president of Haiti in 1971 when his father, Francois “Papa Doc” Duvalier died. Baby Doc was known for torturing his opponents, and was accused of massive embezzlement; many considered him more of a dictator than a president. A popular revolt overthrew Baby Doc in 1986, ending nearly three decades of Duvalier rule. What are the implications of Baby Doc's return to the country in unstable times? Does the former leader return to lend aid or grasp political opportunity?

More protests are expected in Haiti today, and schools, businesses and airports have been closed do to violence. The unrest follows the announcement of the country's preliminary presidential election results earlier this week, which many say suffered from widespread voter fraud and other issues. Joining us for more on the story is Jacqueline Charles, Caribbean correspondent for The Miami Herald.  

Both voters and candidates are calling yesterday's elections in Haiti invalid, citing widespread fraud. Twelve of the nineteen presidential candidates held a press conference yesterday afternoon calling for the vote to be canceled, and protesters took to the streets after scores of complaints from those whose names did not appear on the rolls at polling stations were unable to vote.

UN officials announced this week that cholera is now projected to spread across Haiti more than twice as fast as originally estimated, with more than 425,000 cases expected in the first six months since it appeared. The disease had officially infected 66,593 people and killed 1,523 as of Monday, according to the country's Ministry of Health.

Demonstrators in Haiti have been protesting an outbreak of cholera, which has killed more than 1,000 people and has hospitalized more than 16,000 in the past month. The riots began on Monday in northern and central Haiti, over suspicions that U.N. peacekeepers had brought the epidemic to the country from Nepal. But protesters have also used the issue to make a political statement, burning campaign posters of Jude Celestin, the candidate of President Rene Preval's Unity Party – just ahead of national elections coming up on November 28th, 2010. 

Haitians officials have issued a hurricane warning as Tropical Storm Tomas barrels towards the beleaguered nation. More than one million earthquake survivors have been advised to leave their tent camps before Tomas arrives, which is expected sometime tomorrow. Besides the issue that most of these refugees have no place to go, the hurricane is expected to make the recent cholera epidemic in the country worse. Elysia Nisan, an aid worker for Save the Children, and Jacqueline Charles of The Miami Herald join us from Miami.

This week we’ve been talking a lot about the people and groups financially supporting political candidates in the mid-terms. But there is another national election we’re following where American money could have a major influence. Haiti’s presidential election is on November 28th. Candidates in that election have been actively campaigning State-side to raise money.

A powerful earthquake tore through Haiti Tuesday night, leaving devastation in its wake. The dead and injured lay in the streets even as strong aftershocks continued in what was the biggest quake to hit Haiti in more than 200 years.
