The way I read it, the question was about whom people trust most and least - e.g. different people were the alternatives in the question, not trust/distrust.

Regarding Zhirinovski, also consider the Le Pen effect: he may be third due to the votes of the wide majority going many ways, but that doesn't mean he stands a chance in hell in a runoff.

The majority have a pretty good name recognition, just not a positive one. I think the general sense is that politicians from Yeltsin's time should go; at the same time at the moment neither Duma (parliament) nor the Government enjoy high approval ratings, and that reflects on number of politicians.

Some of the ratings are managed to keep them lower. Say, when Rogozin (Rodina) became too popular, his party was denied elections in few regions and was quickly labeled as a "fascist" in the press.
