Oh, I missread. Khodorkovsky is the guy that used to steal all the money from our country together with other guys in 90's, then was repressed, because our government decided so. After jail, he emigrated and started to constantly cry on Twitter, shit on Putin, et cetera, and now you, pals, think he's a good guy? I'm sure if he wasn't repressed, he would still steal money from our country.
Navalny is a better option. However, he's simply a populist - he doesn't have political views, but being "for all god and against all bad." Navalny as an icebreaker could be a good thing, nothing much more.
