Maguindanao Governor Esmael Mangudadatu (fifth from right, in white) prays before the grave of his wife, Genalyn, in Buluan town before driving to the Commission on Elections office in Maguindanao on Thursday to file his candidacy for reelection. Mangudadatu took the same route his wife and 57 others did before they were killed in the 'Maguindanao Massacre' of 2009.
