He used to be the dance music commissar, and the man who promoted Jacob Zuma among the masses in the campaign to land him the ANC presidency in Polokwane in 2007. Now Eugene Mthethwa, a member of the legendary kwaito group Trompies, has turned on the president."It started with him not picking up my calls last year. He then blocked my number deliberately. I just cannot get through to him. He never returns e-mails and SMSes," said the man known as Donald Duck in music circles.Mthethwa and others met Zuma in 2005, at his official residence on the day former president Thabo Mbeki fired him as deputy president."We had no idea that he was in the middle of a crisis and that he had just lost his job, but he never showed it.story_article_left1"He was in a jovial mood and even shared with us his knowledge of jazz music," Mthethwa recalled.Once they realised what had happened, Mthethwa said, they were amazed by his calmness.He decided to help Zuma by mobilising the music industry to rally behind him, and also did so during his rape trial. In 2009, he recorded songs that had been used in Zuma's campaign for the ANC presidency. In the process he met with the president personally on three other occasions, Mthethwa said.When Zuma became president of the country, he hired Mthethwa to head the Presidential Hotline.Mthethwa left the Presidency three years later to pursue interests in the music industry.But last week, Mthethwa took to Facebook to share his unhappiness with the party and with Zuma - although he insisted he would remain a member of the ANC."Nothing personal, I come a long way with the president, but I cannot choose him over the ANC. A person who cannot do his or her own introspection, scrutinise himself ... he or she needs no second chance in life and his or her case is hopeless," he wrote.His post drew much interest from his Facebook friends, who wanted to know what had gone wrong. Mthethwa told them Zuma had "distanced himself from all those that stood with him genuinely because of the pain they felt when he was under attack".He added: "He surrounded himself with capitalists who are in the process of compromising him and leading him astray."Asked to name some of the people Zuma had abandoned, Mthethwa said: "He betrayed the likes of Julius [Malema], [Zwelinzima] Vavi, [Fikile] Mbalula and others. The forsaken were genuine people who, like me, joined the ANC as volunteers."We cannot all be seen as blind loyalists of the president when he's no longer able to serve the mass democratic revolution to better the lives of the poor than that of certain individuals."Baba is old now and maybe his memory is depreciating."..
