Any poll is subject to influences, cheating, biases, etc, etc... Just spend a week there during not so high season, so you meet mostly locals, and speak to some random people. It takes some effort probably but in my believe it is the only way to make at least a little informed opinion on any topic.
Russia is information autocracy state. TV controlled by state for more than 20 years. Average Russian knows all sort of weird things, basically everything that helps Putin. West is evil, Putin is the only choice, Ukraine is fascist state, Russian is superior culture.
Liberals are better, yet their culture is based on occupation, it brings joy. Annexation of Crimea have raised Putin rating to 87%.
