What is the main idea of the news item? [br] [originaltext] Russians turned

Russians turned out on a sunny Saturday afternoon in Moscow for two rival protests against corruption, the top issue on voters’ minds in this election year according to polls.
    This tale of two protests speaks volumes about the state of democracy in Russia—20 years after the fall of the Soviet Union.
    The state threw its weight fully behind the official anti-corruption protest.
    One day in advance Moscow officials blocked off a one kilometer long avenue for the demonstration. The avenue was conveniently located between a 10-lane highway and transit center with two subway and three commuter rail stations.
    Chartered buses brought in participants, who were issued flags, banners and crisp white "anti corruption" aprons. Numbering in the thousands, they then marched in groups into the protest zone. There, eight massive video screens and a powerful music system thumped out techno music and anti corruption messages.
    Each unit chanted its place of origin, in this case Moscow. The protest was organized by Nashi, widely seen as a youth wing of the ruling United Russia party.
