Aleksei Navalny is indeed a de-facto leader of Russian opposition.
>- He isn't coming second in any polls
Not true. [1] is the only major election in which Aleksei personally participated. He came second with huge gap between him and the third one (despite state-organized media campaign against him).
Moreover, it seems you misunderstand Russian political climate. There are no real political parties here except those loyal to Putin. Most "candidates" in that wiki list are sock puppets with the exceptions of Navalny and Khodorkovsky. Khodorkovsky is not really a politician at this point, so your ironic assessment of
> journalists act as if there are only two politicians in Russia, Putin and this other guy
…is actually true.
Here are a couple of other data points for ya:
- Navalny's NGO called FBK (Фонд Борьбы с Коррупцией, Anti-Corruption Fund) made two biggest investigations to date: on Chayka (Russian's Prosecutor General) [2] and on Medvedev (our prime minister) [3] ([4]). They have more than 20M views between them on Youtube alone (there are countless copies on other social networks) and the latter triggered biggest demonstrations in 5 years.
- FBK voluntarily publishes financial reports which you can find here [5]. According to them, FBK got 40 million rubles in donations during 2015. This alone makes them most-donated-to political NGO in Russia by far.
All in all, I believe this particular fact check lead you astray.
