Extreme liberties in the use of the word ‘presumptive’

I CAN see from my Google check today that labeling Davao City Mayor Rodrigo Duterte as “presumptive president” of the Philippines has now become a fait accompli in local media.

This is despite the fact that “presumptive,” which has been aptly described as “painful to the eye and ear” by a columnist of another national newspaper, is logically and semantically wrong considering (a) the candidate’s astonishing landslide victory, (b) the conceding in quick succession by the top three of his four opponents, and (c) every other evidence available to the senses of normal individuals.
