And what happens if democracy has declined? Dies it come back?
Idk. It just seems like people aren't "into" liberal democracy right now, lol. Democracy is incompatible with hate, fear, and apathy, they break the system.
In Russia this year, voter turnout was 16% in St Petersburg, 20% in Moscow. If people actually cared and demanded their votes be counted, these municipalities could possibly throw Putin out on his ass by themselves. For whatever reason though, they don't.
So in a sense, it is kind of the responsibility of the electorate to protect itself. Maybe people will eventually wake the F up and reverse the trend. But it's not looking likely in the near term IMO.
