Kenyans will go to the polls on August 9th to elect a new president. The current president, Uhuru Kenyatta, is term limited from seeking re-election and the two main candidates are both very familiar figures in Kenyan politics.  William Ruto is currently the Deputy to President Kenyatta. But the two men had a falling out and now President Kenyatta is backing Ruto's main rival, Raila Odinga. For his part, this is Odinga's fifth time running for president.  Kenya has a recent history of highly competitive elections that are sometimes accompanied by violence. Disputed elections in 2007 lead to over 1,000 people killed and hundreds of thousands displaced from their homes. On the line with me to help make sense of all this political intrigue and explain the significance of these elections is Caroline Kimeu. East Africa Correspondent for The Guardian.
