Realistically, I'm not going to enforce a definition. Use your own. The use of the word was deliberate, so it shouldn't merely be democratic socialist or conservative authoritarian. I would suggest that totalitarianism should mean an ideological state with a blurring of party, state and masses. I would also suggest such things would be relative to the timeline if a similar concept to totalitarianism even exists. For example, if syndicalisms of the various varieties were the only ideologies to transform states in such a timeline.
In that case I can't tick any of the boxes with any confidence, though Russia (or part of it if it is dismembered) could be totalitarian as OTL, probably left but conceivably right depending how things go in its civil war.
