Ariel Cohen, writing on the National Interest website:
In late August, Russian president Dmitry Medvedev appointed Georgy Poltavchenko governor of St. Petersburg. Poltavchenko has served as presidential envoy to Russia’s central-administrative district since 2000. More importantly, he is a loyalist to Prime Minister Vladimir Putin and a KGB veteran. He replaces Valentina Matviyenko, another Putin confidante, who has moved on to chair the Federation Council, the upper house of the Russian Parliament. Sergey Mironov, the former speaker of the Federation Council, is out. All this game of musical chairs has little to do with either President Medvedev or significant democratic developments. Rather, it demonstrates how Putin is rearranging his insiders.
