Members within the ruling National Democratic Congress (NDC) who are said to be disaffected over President John Mahama's appointments are planning to put up a challenger to his candidature for the 2016 elections, reports The Finder newspaper.According to some members of the Youth Forum of the NDC, certain individuals within the party who were largely loyal to the late President John Atta Mills have embarked on a psychological warfare aimed at chipping away at President Mahama's support within the party.Two of the whistleblowers, Mr Saminu Mohammed and Paapa B told The Finder on Sunday that they had evidence to show that some Mills loyalists who were unhappy about the President's appointments were fuelling disaffection in the party."A whole regional youth organiser of the party during a recent meeting in the Eastern Region got up and said President John Mahama is destroying the party for them and they will not sit down for him to destroy the party," said Mr Mohammed who is also the Chairman of Grassroots thinkers of the party.The youth organiser's grievance, according to the whistleblowers, was that the new appointees of the President at the Flagstaff House do not know them or accord them the appropriate recognition.Mr Mohammed alleged that some old faces in the previous Mills' government are bent on ensuring that President Mahama does not go for a second term."They are funding a candidate to contest the President," the whistle blowers maintained.According to Mohammed, he had received reports of people within the party spewing falsehoods about President Mahama."Whoever they are talking about who wants to compete with President Mahama come 2016, we are equally ready for that person. The person should not be a coward, he should come out," he dared.
