MANILA, PHILIPPINES - APRIL 23:  Philippine presidential candidate Rodrigo Duterte listens to political speeches during a campaign rally on April 23, 2016 in Manila, Philippines. The tough-talking mayor of Davao in the southern Philippine island of Mindanao is currently leading in presidential surveys but has caused uproar on comments over him joking that he should have been first in line to rape an Australian missionary before she was murdered during a jail siege in 1989. The controversial presidential hopeful has also lashed out at US and Australian embassies for criticizing his comments and has threatened to cut ties with both countries in one campaign rally. The Philippine presidential campaign ends on May 7 with elections slated on May 9 and features 5 presidential candidates vying for the top post.  (Photo by Dondi Tawatao/Getty Images)
