here
is Putin's comment. He said: "we need to work rhythmically. We can't afford losing time looking for new people. Since everybody already knows each other and creating new connections will take to much time".
It's like you MUST change your wife and kids every 6 years. Doesn't make any sense actually, if you don't want to. And that's the only thing that matters.
Basically everybody seems to be happy about it. So we can't really blame Putin, or Valentina Tereshkova, the cosmonaut, who proposed to reset his term. So he can enjoy more time in the chair. Unfortunately they also reset Medvedev's terms, who was unpopular, but he's unlikely to run for anything in the near future.
Russians are motivated to avoid crisis.
Besides, they didnt like the constitution of 1993. Why people had to live in a democracy out of the blue. Nobody even explained to them that "it's the only way to go", when they were young enough to think critically, maybe in kindergarten! Indeed the adults didn't want any of this. And their feelings? Are they any less valid than feelings of American patriots? Do people who defend democratic values even realize how arbitrary those values are?
Presumably nobody likes the old president after 4, maximum 8 years. Half of them didn't like him to begin with. And the elections were only an excuse to raise money and insult other candidate for a show. Two favorite pastimes. Then they begin to come up with more shows. "Who wants war in Russia vs war in China? Which country do we have to take down next? And we all need to raise money for it!"
You can sell this only to those who have to buy it. But not to anyone else! How authoritarian is that.
