I am talking most recent growth rates in membership, as a percentage, to account for the difference in time periods the respective parties gained popularity.
The Socialist Democrats can be considered Communist because of their reparations and 90% corporate tax rate rhetoric, among other things. I have not included the Green Party or any of the other Socialist Partys.
All the support Bernie Sanders received in the primaries versus Hilary and Biden, which people were behind it and what would you say their favorite economic system is? Remember Bernies platform? Bernie almost took down both Hillary and Biden, before some “Special” moves were made by Hilary and the Democratic Party.
Below are a couple of articles that talk about membership growth of the Libertarians and the Socialists. I don’t have time to do a thorough breakdown as I’m working all day. Give the word and a day or so, and I’ll do it. Remember, my focus is recent relative performance between the parties.

So even if Libertarian official memberships are still greater than the Democratic Socialists, the number of actual supporters of the candidates seems to strongly favor the Socialists over the Libertarians.
One thing is for certain, The Socialists have been gaining ground versus the Libertarians recently in voting power and maybe even in relative difference of total political offices held. To be clear, the Libertarians still hold more total offices, including local, state, and national. But not for long if trends continue.
