Putin is where he is because he doesn't hesitate to kill each and every person that questions his authority, you can't expect people in an environment like that to go out onto the streets to demand the dictators head because it will end in a very predictable way. But the general impression I get is that people are broadly visibly supportive but in private a lot less so if not outright against it. This makes it very hard to measure the temperature in Russia. There is a good reason why Putin keeps murdering the opposition (or removing them in other ways): he knows that if there is a fair election and a half decent challenger that he's history.
