No they got these 11,5% as a Liberal Democratic Party of Russia.
Regardless, I have not met a Russian who supported Zhirinovsky's crazy ideas.
I have not met either. That is one of the reasons that I think that Russian elections was rigged. Zhirinivsky has such role in Putins regime to make controversial statements. As a member of oppositionist party he can do what he want, and Putin is not the one to blame. On the other hands, more Russian voters seeing that he is an idiot (like Rodina and the communist ) vote for United Russia, the only reliable party. (democratic opposition is marginalized in Kremlins controlled media outlets) In fact Zhirinovsky supports eventual Putins attempt for the third cadency. So despite his idiotic statements (far from official Kremlin line) he is still cheering for Putin.
However there is popular saying that whatever Zhirinovsky talking, Kremlin is thinking. :-)
