Koko Pimentel or Migz Zubiri? I'm sorry if I sound pessimistic, but after listening to this interesting comment by Defensor, I'm DEFINITELY picking Zubiri to get more COMELEC generated votes in Mindanao.
Unless Zubiri preempts the COMELEC declaring him the victor by conceding first. ;)
(And if he does, I'm sure he will write another beautiful concession speech like Gore, Recto and Defensor).
