For some reason individuals in Russia think that if the candidate they were voting for did not win the elections - it means the elections were not free and somehow fake, but you have to understand that there are a vast majority of people in Russia who thought that Putin is a better candidate compared to Prokhorov and others
For example, Moscow voted as two different cities: https://github.com/alamar/elegraph/blob/master/moscow.png Note the two obvious centers of blobs. I'm yet to see any non-handwavy explanation of that phenomenon, and why it then disappeared for the next President elections.
There would be a few outliers and a massive core of "typical" districts with similar results in them. We're even bound to get Gauss distribution of results or something similar.
However, for Duma election, there's no continuity. There are two distinct profiles. There are a lot of districts with one kind of results, a lot of districts with different kind of results. As if it was two different cities, possibly in two different countries. Or if election results were rigged in a large subset of districts.
Why would that be?

One just should not use "external abuse" as reason to act (or not).
You're assuming that free elections would benefit common Russians. They wouldn't. You're right about one thing, though: it wouldn't be Putin and his cronies siphoning all of Russia's wealth (resourceful citizens, natural resources, ...). It would be the western conglomerates.
