could say it was the same for obama (back fired hugely ) . but even before , putins ratings were above 60% which is still pretty high .
most western leaders would die for such ratings 
putin has done alot of good for russia , dealt with the corruption , where the oligarchs basically run russia , until putin basically stabbed them all in the back after they got him in power 
but as you rightly point out a few posts ago , russians dont want freedom like we enjoy .
they want a strong leader and one that will stand up to the outside world
