How come Russia wasn't "decommunized" as much as other eastern bloc countries?

Countries like Ukraine and Poland banned Communist parties and Communist symbols, while Russia didn't. Ukraine demolished statues of Lenin, while Russia still keeps him preserved at his mausoleum.

Is there a reason why anti-communist sentiment is (or at least seems to be) much stronger in other former socialist countries compared to Russia?

Did Russian Communists manage to still remain powerful enough to force concessions?
