I don't know about your country but in my country, politicians buy over media empires to sell lies and propaganda to the public... I know this is not peculiar to my country. This may be the reason there is a growing distrust between the leaders and the followers.
But is politics supposed to really be about lies? Why is the polity dominating by propaganda?
Actually it's also very common in my country, politicians are all an ambassador of liars, because it evolves in their everyday activities, I know that almost all of the politicians in my country are lying just to cover up for their incompetence, and most times they do that by lying how their predecessors does so many things that it's very clear that it's not true, but we as nationals in the state, we knows better and how cunning they are when it comes to lying.
The most sad aspect of it is how they have buy the minds of most people in the state, including the judiciary and media as the op has
already said, they will see black and call it white because they have been bought over, which is very sad and regrettable.
