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.
It's the same here. The real name for it always used to be channel 1, but since it's only government propaganda they call it "government tv" in the free media.
Different governments use the same tactics because they learn from each other. If something works for one country it may work for another.
But is politics supposed to really be about lies? Why is the polity dominating by propaganda?
No, it's not. In most countries it's about buying votes and you can buy them by promising stuff to your voters, giving them freebies, lying to them, scaring them with war, or pandemic, or lack of money...
There's many ways to get votes. For instance, in Russia they like to simply print additional ballots and cheat the system the good old way.
