If Russia is like the US with trump, then there’s the active population who are supporting Putin, because even if he’s a bastard, at least he hurts the right people. Then there’s an apathetic horde, who don’t care or are too beaten down to do anything. Then there’s the group that know what’s up and wants change.
The question is if Navalny’s death meant anything. The people who care are already at a disadvantage because of the authoritarian State, the supporters aren’t going to change, and the apathetic don’t have time to care. IMO he would have been better off, alive, outside of Russia and criticizing Putin.
