Governments and governance systems are supposed to find ways and means to bring about development to the country and improve the lives and livelihoods of the citizens. In the process of doing this, systems and institutions are what matter.
Mostly, it does not matter which individual occupies a particular position as long as the systems and policies are in place. This is why it is important to ensure that there is what is called institutional memory so that whoever occupies the office will continue from where the predecessor left.
If this is the case and everyone understands and sees it in this light, then all political debates should focus on issues and policies instead of concentrating on individuals and personalities.
The other advantage of basing the political discourse on policies instead of personalities is that it helps promote detachment and objectivity. This is what will bring out the best from the people who take part in the debates to formulate excellent systems for the furtherance of the nation.
