Because Pacquiao doesn't have enough money to run his political campaigns now. His dream is to become the president of his own country in the future and it will require a huge sum of money to fulfil such a dream. So what else can provide him that huge amount of money but boxing? Sooner or later he 'll be back in the ring. Mark my words. Any comment?
He loves helping the poor in Philippines so he will donate a huge sum of his money to them like he used to do, and one day he will find that most of his money is gone.
Of course he will, jmm 5 thru 10 and bradley 4,5 + only safe fights for pac. He's going to rob his gullible cult a few more times before bowing out with 10+ losses
