As polls show, the overwhelming majority of Russians regret the collapse of the Soviet Union. We should note that from poll to poll, the share such people has remained high (data in % of those surveyed):

People who... 1992 1997 1999 2001 regret the collapse of the USSR 69 84 85 79 don't regret the collapse of the USSR 32 15 11 15

So it is quite logical that when answering the question: "IF A REFERENDUM ON CONSOLIDATION OF ALL THE FORMER USSR REPUBLICS WERE CONDUCTED TODAY, WOULD YOU VOTE FOR SUCH CONSOLIDATION OR NOT?", the majority of those surveyed (72%) said they would vote for it, while 15% of Russians would vote against it.

However, most respondents (58%) avowed the obvious fact: there is no chance of restoring the USSR. 30% of respondents still cherish hopes for the restoration of the USSR. Zyuganov supporters (49%), people with an incomplete secondary education (37%), and those over 50 (36%) were more likely than others to cherish such illusions.
