No, he wasn't vice president.

from your link:

He is the first Philippine candidate to lose a vice presidential campaign but win the presidency.

And about Duterte, exactly my point; imagine the level of competence it takes to run such a crazy (and sorry to say so, but successful) war on drugs while (probably) being involved in drug trading yourself! And then all the other crazy shit he did. The dude had more than just brains and passion, while Bongbong seems to care mostly about his daddy's reputation.
