I am of course comparing to the USSR, not modern Russia. Pretty much the entire "progressive" wing of the party, with its anti-capitalism and fostering massive welfare state dependency, as well as the recent focus on "oppression" and "power", and purity testing.
I am pretty meh/cynical about the economic aspects, actually; sure, I think these are bad ideas, but unless they run the thing entirely into the ground, I believe there's going to be enough for me until old age at this point, and of course I view legally abusing government programs as libertarian activism - e.g. if there's universal healthcare it would make it so much easier to retire early and use it for all it's worth ;)
What I am actually genuinely afraid of is the cultural garbage, esp. as it infiltrates the education system. See the capitalism/socialism approval polls among the young people, etc.
USSR has collapsed when I was 7, but I was still brainwashed enough that I remember asking my parents about the English Premier League - how come they have soccer in England? I was surprised because I thought it was a capitalist system where everyone was oppressed, so at 6-7 or whatever I didn't understand how they could have a soccer league. That was of course while living with 2 STEM MSc parents and a sister in a 700sqft 2-room flat, not being able to afford a car, and knowing nothing about the actual living conditions in England.
From what I know about the school systems in big cities (I know some people who work at schools who are pretty left-wing and they talk about this stuff as if it was a good thing, plus from the news/leaks to right-wing sources), the oppression/anti-capitalist propaganda is rampant, and the current "far-left" wing of the Democratic party are very popular. If it's between this stuff and dumb nationalist rednecks with whom I disagree on 90% of pretty much everything, I'm going to throw my lot with the rednecks.
