Stances of “Communist Party of the Russian Federation” and “Fair Russia” as two main left parties on the eve of State Duma election-2021 are considered in the article. Based on the analysis of CPRF leaders’ reaction to January protest campaign, the author concludes that there are some signs of crisis within the party and pinpoints reasons of communists’ inability to crucially change their image and electoral resources for the upcoming election. “Fair Russia” attempt to strengthen its potential through alliance with the left and patriotic forces as well as its possible outcomes within the context of rather controversial perception of the party as an oppositional one are evaluated. Objective demand for consolidation of all Russian “left” forces on modern social and democratic platform is substantiated.
