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?
The more you can deceive the people with lies and false arguments, you are the greatest leader of the present time. One of the biggest symptoms in politics is false consolation, taking votes from people with false consolation and stealing votes to become ministers. From history you will notice that almost every country has a crisis in politics, where not even a leader can be found on the path of truth.
