there is also a Religion called INC(Iglesia ni Cristo) in our country which Endorses Presidential and Vice presidential candidates to the people in their religion and asks them to support the Politician the religion endorsed.
It is wrong for religious leaders to be campaigning for politicians or supporting politicians openly. What the religious leaders are supposed to do is to correct and preach about bad leadership. Religious leaders don't have anything to do with politics or campaigning for politicians, it will cause a lot of damages in the society.
