I just don't see how it's possible to consider USSR policy in relation to Democrat party politics. I think it's a false comparison on so many levels that I wouldn't know where to begin with the numerous arguments. I suppose you are seeing these false comparisons elsewhere, because Republican disinformation politics has tried to paint Democrats as 'Communists', 'Nazis', 'Socialists', and as exactly the same as Republicans (the 'both parties are the same' argument). It's part of decades of a barrage of attacks on anyone associated with the Democratic party. There are so many conflicting claims because the lies are also numerous. It's the only way in which Republicans can be elected. They are not supportive of anything beneficial, as they focus entirely on what they are against (anti-democracy, anti-education, anti-voter, anti-environment, anti-climate-change, anti-human rights, anti-fair wage, anti-union, anti-public school, anti-library, anti-teacher, anti-non-binary, anti-women's rights, anti-abortion, anti-middle-class, anti-tax the rich, anti-social programs, anti-veteran, anti-healthcare, anti-medicare, anti-Social Security, anti-Ukraine, anti-gun laws, anti-everything). There is nothing the Republicans want to support that is beneficial to the 99%, nothing at all. If you want to compare this with the USSR, look at the rise of income inequality in the US since Reagan, thanks to Republican-controlled congresses for most of 40 years. Democrats are famous for wanting to spread the wealth - sometimes criticized as "redistributionists". But what's really at issue is that tax dodging rich people should pay their fair share of taxes, and that the quailty of life for the middle and lower classes need to improve, which can happen ONLY with progressive politics.
