Duterte wants to tap the support of Iglesia Ni Cristo, popularly known for its practice of bloc voting.
A Philippine Star report said that Davao City Mayor Rodrigo Duterte asked for the religious organization's endorsement in a private letter.
INC, however, has yet to release any statement regarding the matter.
The Bloc Vote
Iglesia Ni Cristo, over the years, has maintained a reputation of being a gold mine of votes, promising the support of its followers for anyone their leader would point to.
But how united is the INC?
During the 2010 elections, Noynoy Aquino was endorsed by Bro. Eduardo V. Manalo, the executive minister of the INC.
According to Politiko, Social Weather Stations (SWS) chief Mahar Mangahas said that the SWS exit poll was indicative of how united the INC was at that time, albeit only to an extent.
The poll showed that 77% of INC voters supported Noynoy Aquino, as opposed to the 12% that chose now Manila Mayor Joseph Estrada.
Mangahas said: "The 77 percent is the extent of unity of the INC vote—not 100 percent, but quite a lot.”
She also said that the INC accounted for 1.53 million of over 36 million votes cast for the top two positions in the national elections in 2010.
