Actually, the ideologies of the parties are:
UR - Serious unconditional support for the government
LDPR - Unconditional support for the government and circus-style clowning around
JR - Bleeding heart support for the government with a whimper
Commies - Fascism
I guess, that's about right.
Do leftist intellectual types even bother associating with the Communists in Russia? It strikes me that in former one party states of the left, that most support for the original ruling party comes from old-timer flag wavers with little to no support from the urban middle class.
