Article 81.3 of the Russian constitution states: "No one person shall hold the office of President of the Russian Federation for more than two terms in succession."
So if Putin steps down (surprise!) and Zubkov takes over before the elections, Putin could run again, right? Just another theory.
Another fun quote: "Acting Russian Prime Minister Mikhail Fradkov said Wednesday he has no doubts parliament will approve the head of the country's financial regulator as the new premier. He also said he was sure the new government will continue the course led by the dismissed government."
Well, of course.
