So many of those politicians have a good plans and a good heart to foster the interest of their citizens but what causes their limitations most times is that fact that they have their obligations to obey and fulfill the instructions given to them by their political godfathers, if only it can be possible for anyone to assume a political position without such figure of a political godfathers definitely there will be a more better less corrupted politicians in various countries where there is this abuse and mis appropriation of political powers, this has the order of the out day and until such manipulation and orders will be put to a stop there is no going to a positive change in this regards.
A friend told me that every politician derive a new definition of politics the moment they get a position in power. Indeed no one has ever gotten a political post without the help of other people, not just the godfather, who have special interests why they issued assistance during the election period. It could be for business growth or contract manipulation during the regime, and it's wrong on the leader's end to avoid his party members, as he'd require them in the next coming election. So, the economy of a nation revolves mostly around those in political power, while the voters have to wish for a better leader someday.
