I see where you are coming from but those are pretty harsh statements to make.

Pacquiao had gone to a point where he fights even an unknown fighter: Surely you did not mean this?
Desperate for a win that will favor him in the elections: Like he needs more popularity
Pacman does not really care about boxing: What do you care what he cares about?
All he cares about is earning money: He gives back right?
Does not deserve praises: Because he joined politics? geez

I don't like Pacman running but I am not as frustrated as you are. I still believe that mo matter how much of a public figure Pacman is and how significant his boxing career for Filipinos he is still an individual that has the right to do what he wants. The guy is a pro athlete getting beat around the ring for a living, how much care for boxing do you need to see?
Pacman has all the right to run, if he wins and mess up big time then go critic his public office not his boxing.
