Ex-president Jerry John Rawlings declined on Tuesday to reveal which of the presidential candidates he will vote for in the December 7 elections.In an interview following a meeting with Nigerian ex-president Olusegun Obasanjo, he conceded that incumbent President John Mahama has a good deal of support but stopped short of confirming whether or not he will vote for him on Friday.The statement comes two days after Rawlings’s office issued a press release declaring his support for President Mahama.The ex-president also criticized some members of the governing National Democratic Congress who he said lack integrity.He singled out the Member of Parliament for South Tongu, Koblah Mensah Woyome, who he accused of corruption.
