To be fair, the EFSR is still a very left-leaning democracy. Most of the opposition parties are token or wouldn't change that much given power - much like bourgeois democracy. Make no mistake, we are still socialist, and we're better off for it. We still follow Marxism-Leninism, and this idea that we've somehow abandoned our socialist routes is ridiculous. Our limited free market experiments have been helpful, but we are in no danger of capitulating to capitalism any time soon. We see this as more like the New Economic Policy than 'proper' capitalism, anyway. Besides, the Republic of China is often at odds with the EFSR, they just don't act like it to foreigners. Even if the RoC has more geopolitical power at the end of the day.
The major parties of the EFSR are as follows:
The Communist Party of the EFSR (CPEFSR) - Marxism-Leninism
The Marxist Party of the EFSR (MPEFSR) - Controlled opposition, anything from Trotskyites to 'left-wing' communists
The Communist Party of the EFSR - Centrist (CPEFSR - C) - Marxism-Leninism but with even less tolerance for diversity or neo-Marxist thought than the CPEFSR.
Liberty - The social-democrats and cooperative-fans who seek, well, 'democratic socialism' - or milquetoast social democracy.
Infiltrated parties:
The Communist Party of the EFSR - Traditional (CPEFSR-T) - What you in the west might call "National Bolsheviks"
The National Socialist Party of the EFSR - The name makes them clear enough.
Freedom - Not to be confused with Liberty, Freedom is a mess of centrists, conservatives of varying stripes, libertarians, and the odd anarcho-capitalist. There's more NKVD agents in this party than legitimate members.
The Communist Party of the Forgotten Many (CPFM) - A bloc for minorities, mostly, still full of NKVD spies, but not as much as Freedom
Banned parties:
Various terrorist groups
Various secessionist groups
Various non-CPFM parties for the rights of non-ethnic Russians
The Eastern Nazi Party
