it has always been that way

like LP made Noynoy run after Cory died simply coz he's the son (Cory's death boosted the Aquino brand)

Mar Roxas was supposed to be LP's presidential candidate pero they talked him out of it

they made Roxas run for VP nalang coz the Aquino surname offers higher chance of winning

-

like Erap (after being deposed) convinced his good friend FPJ to run for president coz if FPJ wins parang bumalik narin siya sa kapangyarihan
