Russia is a democratic nation, and a federal republic which does not have the ideas of collective ownership, as is seen by the emergence of highly affluent young russians, something not allowed by a strictly communist system. It could be argued, academically, that the true idea of a communist state set out in Marx's 'communist manifesto' and other writings, was never achieved in Russia, nor has it been achieved anywhere, thus making the answer 'no, Russia has never been communist, but was for some time a totalitarian state set up along the lines of communism'. However, this would be to delve too deep into semantics. At present, Russia has seen attacks from the media over some of its policies, which have been seen as a return to a very centralised, controlling government.
Russia is a unique nation, and in the post-soviet era, is still in a state of flux, politically, economically, and socially. You can never say never, but in my opinion Russia will not be communist in the forseeable future, as the system is not, in my opinion, workable in the current world environment.
To link slightly more to the election, I feel that as representative for Russia, I would need to manage the unique political situation in Russia, and convey what is going on in Russia to the rest of the MUN.
