Ghanaian actor has said the flagbearer of the opposition National Democratic Congress (NDC), John Mahama, wanting to be elected as president again is an insult to the entire Ghana.  According to him, he does not see why Mr. Mahama, after serving in public office from being an Assembly member through to an MP and then President, should still want to return to the presidency.  Speaking on GHOne TV, monitored by GhanaWeb, said he believes John Mahama has seen it all in public office, and there's nothing more he can offer to further develop Ghana.  "He has been an assemblyman, a Minister of Information, he has been a Parliamentarian, he has been a vice president; technically, he was more like the president when late Atta Mills was in power because he was sick. So, he was more like the person running the show from behind. Then he became president.  "I don't have a problem with the man; he is such a nice gentleman. He has done enough for Ghana.
