The problem with a democratic system in which the government officials are elected by majority vote is that it absolutely precludes honesty and sincerity on the part of the person running for election.
This is especially true during the campaign to be elected because their purpose is not to run the country well, but rather to be elected.
And so they will say anything the people want to hear so they attain their goal of political position. Then the people say what a liar he or she is.
The problem lies in the people wanting to hear good things, instead of Truth.
In this case, people blind themselves to the obvious reality and believe lies. Then they can complain that the other guy is a liar when in fact, you are the fool who believed an obvious lie.
This is how people avoid responsibility for their own lives and choices. It is far easier to blame another person than to accept you chose to believe a happy lie instead of a harder truth.
How much suffering do you cause yourself throughout your life by doing this, for politics of friends or anything at all.
End your suffering by seeking truth and then you will not be disappointed when you see the liar caught in his lie because you will have seen it coming from the outset.
One more liar to observe, and the cunningest one of all, is your self.
