Without independent media, how can we trust the approval rating is accurate?
Levada-Center is the best bet we have: https://www.levada.ru/en/ratings/ But when even Russians who live in Germany are rallying in support of the Russia's war it is reasonable to assume that those ratings are accurate.
The "living in germany" part doesn't contradict the same concerns that those living in russia have, as like those living in russia, the emigrated russians likely have:
- family still in russia - ties to russia (financial, business, family, etc) - desire to visit russia without having to deal with legal harassment for actions done abroad - desire to be able to assist people (family/friends) living in russia without compromising them
This does not mean that they are for or against a current government, but rather, that the proposed logic is specious as it tries to create a separation where it is not probable there is one while simultaneously extrapolating the results of a small sample size across a population that supposedly is without the influence of Russia.
