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?
In power you will see the eagerness and inquisitiveness to have willing power to control and subjugate people under them. But the bitter things about politics is that they are usually known as people who aren't sincere or that can do all things be it staining their hands to acquire such power, they would do it with all necessary measures. That is why we must learn to avoid politicians and if you watch carefully I barely post here as I do dislike politics. In all, all politicians are liers and they don't keep to their promises.
