NAIROBI – BPresident Uhuru Kenyatta on Monday was declared the overwhelming winner of a rerun election boycotted by Kenya's main opposition leader, collecting 98 percent of the vote but also exposing the divisions roiling this East African country. While Kenyatta's backers celebrated his re-election, angry supporters of his rival, Raila Odinga, skirmished with police in Nairobi slums and burned tires in Kisumu, one of the opposition strongholds in western Kenya. Kenya's election commission said the turnout of registered voters in the Oct. 26 election was about 40 percent, compared with roughly twice that in August balloting that was nullified by the Supreme Court because of what it called "irregularities and illegalities." The rerun was marred by deadly clashes between police and Odinga supporters in the days that followed. Kenyatta said he expected Odinga followers to mount new legal challenges, indicating the long saga that has left many Kenyans weary of conflict and has hurt business in East Africa's economic hub is not over.
