Mauritania Presidential Hopefuls Conclude Campaigns Esha Sarai NOUAKCHOTT - Six presidential hopefuls in Mauritania ended their campaigns on Thursday with hourslong rallies throughout the capital of Nouakchott. For the first time since a 2008 coup, President Mohamed Ould Abdel Aziz will not be up for re-election, leaving the polls wide open and voters newly energized for change. Among the opposition candidates are Sidi Mohamed Ould Boubacar of Tawassoul, the country's main opposition party. Boubacar previously served the country as prime minister from 2005 to 2007. Though he is more established in politics than the other opposition candidates, Boubacar is running on the platform of change, and has said that electing the ruling party's candidate would not affect necessary change in the country. "I think there needs to be a true changeover, because the state today of my country is catastrophic. The economic situation is extremely serious, as are our societal problems," Boubacar told VOA. Another notable opposition candidate is Biram Dah Abeid, an independent politician running on an anti-slavery problem. Mauritania has consistently ranked as one of the worst countries in the world for modern slavery, a problem that Abeid has combatted in his work outside of politics. Abeid has gained popularity among poorer and rural communities, and he says it's because despite his international travels, he has always been committed to the betterment of Mauritania. "I've devoted my life to the Mauritanian people, to fighting slavery, and to fighting racial discrimination," Abeid told VOA. .
