There’s even opponents to Putin who’ve had more electoral success than getting 27% in a mayoral election.
And I’m sure you have the list at hand and ready to inform me, since me, a Russian who lived in Russia until the war started, has no idea who the hell you’re talking about. Please include the examples after 2010 at least, the political activity before that is not super relevant.
I’m waiting for some names, my dude.
Also, LDPR, KPRF and any other smaller bullshit is not opposition, any other opinion is uninformed and/or pro-Putin. Yabloko was opposition until about 2016 but not for longer.
