A political activist said on Sunday President Benigno Aquino 3rd has begun a smear campaign against Vice President Jejomar Binay and other possible presidential contenders from the opposition to sabotage their chances of winning.

“It is clearly hypocritical for President Aquino to unleash his attack dogs against VP Binay and other leaders of the opposition, while shielding himself and his allies from similar demands and mechanisms for accountability,” Dr. Carol Araullo, chairperson of the Bagong Alyansang Makabayan (Bayan), which has anti-government leanings, said in a statement.
