After all the dirt thrown at Binay, i am surprised he is still in with a very good chance. They did the same with Manny Villar a few years ago and he went from being a sure winner to losing his bid to become president.
Not sure about your man Duterte, as even though i agree with a lot of his ideas, he seems to come over as a dictator at times.
If i could vote i would probably go for the very boring Mar Roxas.
