In fact I don't remember there being any real (elected) opposition in Russia, the "multiple parties" have always just been a theater. Like maybe some of the smaller parties would sometimes manage to push some insignificant agenda, but the important issues would always be controlled by the actual leadership in power.
Call me old school, i am a bit skeptical of single perspective foreign country coverage after the Iraq war lies and NYT’s fawning coverage of Stalin’s Russia.
Look up also the amount of journalists murdered there, that isn’t a democracy.
j6 was a singular event, which loosely coalesced around one person to achieve a goal (stop the election being certified, thus "stopping the steal")
at no point did j6 attempt to enter into the democratic system as a party.
