Based off of what Harry said, it looks like Parties 4, 7, and 8 get seats at the moment (plus United Russia). Party 8 is marginal, at 7.2%. United Russia is only at 63.5%.
63.8% is, roughly, what was predicted (probably, the official target set in the Presidential Administraion is within +-2%). 63.8% should translate in about 70% of seats in the Duma - well over any majority that could ever be procedurally necessary. Note also, that "Just Russia"'s main pre-electoral plank has been that it is MORE pro-Putin then Putin's own party, and the Zhirinovsky's LDPR is (and has always been) a creature of the security services (read KGB) and is always pro-government. Thus, the Commies, w/ about 12% of the vote (and, say, 15% of the seats) will be the only opposition - and half of them are on the government payroll as well.
