don't get you hopes up for duterte or even for this proposal of his .... Actually, this has already been proposed during madam arroyo's term but most of the senators and congressman didn't get the idea ...
But let's just assume that duterte has run for the presidential seat and won .........
Nothing good will happen ... Why

Duterte is a newbie in malacanyang .. While most of the senators and congressmen have roots dug very deep in our system. His iron-fist-style won't be effective in malacanyang ... He'll be alone..
That's why, philippines is hopeless ...
