First most of them not smart there is no genius ideas and all they care is just to make people happy and elect them that's it.
That's mostly western political leaders for example USA biden admistration as perfect example.
congrats for realizing that
i am sure that a lot of people would fall victim to propaganda and hype i do not know when will people be able to separate the politicians who can actually do good and politicians who are just popular and relying on their popularity to boost their name you’d be surprised with how much celebrities are running for a position in my country
