You’re doing a thing so you won’t care, but for people who don’t know how that works, right now in Russia there are several laws active that will put you in jail for not being sufficiently enthusiastic about the war, and there is a big number of very well known cases where those laws were enforced with an utmost force, just today I read that 19 years old child who was put in jail for two and a half years for reciting a 19 century poem, was put in jail again for calling the war “criminal” in the interview.
With all that, if you’re Russian in Russia and some polling agency calls you and asks you a question, for you it sounds like “do you totally aggree with what glorious leader is doing or do you want to go to jail”. Hell, my own mother will not talk about the war to me on a signal call in fear that someone is listening anyway.
Not only we don’t know how many people support or not support the war, the whole question can’t be apllied, support as a concept doesn’t exist in a police dictatorship.

There was for sure a lot of voter suppression going on, that much is clear, documented, and pretty much undisputed. They fucking bragged about it for fuck’s sake.
