The leader of the Progressive People’s Party (PPP), Dr. Paa Kwesi Ndoum has said it will be a big mistake on the part of Ghanaians to retain the ruling National Democratic Congress (NDC) in power or give the opposition New Patriotic Party (NPP) another chance to rule.He said Ghanaians should be fed up with the two parties which have not been able to make life comfortable or better for the people.Dr. Ndoum was speaking at the launch of his party’s national campaign for election 2012 at Elmina in the Central region Saturday.Joy News correspondent Richard Kojo Nyarko who was at the launch reported that like David in the bible, the PPP flagbearer believed he would wrest power from the Goliaths in Ghana’s politics to resolve the many challenges confronting Ghanaians.
