They don't even need control. They want control. Why? Either they're idiots who think they need control or they are tyrants who know they'll need control later on when they start doing seriously tyrannical things.
Many politicians are individuals without any talent who desire power and control, politics is the only avenue open to people like that.
> they'll need control later on when they start doing seriously tyrannical things.
You mean like when they start jailing people for social media posts? Or when they are going to ban kitchen knives? Or when they're going to hide a massive gang rape scandal because it makes them look bad? Or when they would convict 900+ people on false charges of fraud because they couldn't admit their computer system was broken? Come on, we all know this is not possible.
