A comment for outsiders: Russian elections are multi-layered. When dominance of Putin and his party is threatened, then the state will employ everything it's power. But within his own party, and on many local levels, there's also a lot of competition — and there, elections can be much less fraudulent. So, those local crooks can't rely on repressive apparatus of the whole state, and have to revert to political technologies and tricks which are usually used in developed democracies.

Boris Vishnevsky, as many other candidates (including my own father) are being elected not through centralised party lists, but through single-mandate districts. (I think it's similar to UK electorate system). And while United Russia (Putin's party) total numbers over the whole country will be very tightly controlled, results of those district-based elections are, in general, much more honest.
