I don't know - we'll have to see what Antonio thinks.
But it's not like the other parties are banned: KPRF is the second biggest with many millions of supporters and members. I doubt they would improve the media situation if they won though....
The reality of the situation is that the majority in Russia seem to prefer Edinaya Rossiya over anything else - and media reflects it.
The interesting question is: What will happen if Edinnaya Rossiya and/or Putin makes some huge mistake, and Russian public opinion turns against them? Will it be possible to openly discuss that in media? Will it be possible to demonstrate against them? Will it be possible to get rid of them in an election?
This said, I think democracy is very hollow in most of Europe too. There are constantly things going on that the majority is against. Only Switzerland has a democracy that I think is genuine, with their referendums...
