The last I heard Sarah Duterte was run for mayor of Davao.
Some of the election rules here are a little strange. According to my wife. Anyone running for a position must declare their candidacy by October 8th. They can change the position they are running for up until October 15th. My guess is if two good candidates from the same party run for the same position they can get shuffled around.
Another strange law allows for a member of the same family to take the place of the declared candidate if the original person is unable to continue the electoral race. I could go on ad nauseam about what could possibly happen but the list is too long.
