Sounds like Putin will have to TAKE power if he wants to run the country after his terms.
Why are you people all hard for such a scenario -It is like you wet dream it - Putin, if he wants can run for prime minister after his term expires or wait 4 years and run for president again (the term limit is only for 2 consecutive terms). I know the new world is not as cool as the old world of the Cold War was - get used to it.
