Not just telling lies but constructive lies because one thing is to tell lies and another thing is to make the ordience believe the lie to be truth. I must say that politicians are professional in making constructive lies to cover their weakness and incompetency especially those corrupt politicians that have nothing to offer to their nations than looting their treasury and institutionalizing corruption and thuggery.
They don't even care about making the audience to believe their lies to be true anymore. When politicians are confronted for the contradictions between their words and actions, they simply order their fanbases to attack the person who is pointing out the politicians to be liars. As consequence, the fanbase won't exactly deny the politician they idolize to be a liar, rather they will simply focus on the lies of the adversaries, claiming that they are much worse than the ones perpetrated by their personal idol. That is what we have been seeing on the political discussions on the internet in social medias platforms.
There is a constant argument going on between dirty and poorly washed people, which won't take society to anywhere in a constructive way. For those who still value their mental sanity, it's advisable to stay away from such conversations and such people, be it on the internet or on physical world. Nowadays it's pretty obvious when someone is lying, due to the speed information reaches us in real time. So, if there is still people believing on these things, let it be. Don't waste your precious time trying to convince them the opposite.
