There are some interesting insights into the political status and prospects of Ukraine's president-elect Poroshenko in this (NB) Valdai Club article. A couple of excerpts:
Statements made by US politicians did not have much influence on Ukrainian voters. More likely, the electorate was swayed by technologies invented by a Ukrainian spin doctor, Igor Gryniv (who was behind the electoral success of Viktor Yushchenko and still earlier planned the establishment of the Reforms and Order and Our Ukraine parties). First of all, he cleaned out the minds of Ukrainian voters and made them accept Poroshenko as a “new politician.” Next he began publishing his growing ratings and convinced the public that his client took the lead in the race. All that remained was to give voters a motivation for support and urge a first-round vote.
The new Ukrainian government’s ability to steer an independent line with regard to the Russian Federation will depend on many factors, including the international situation. The world is volatile. Poroshenko, a flexible politician and diplomat, is unlikely to focus on just one line of behavior. I would not be surprised if the utterly pro-American politician Poroshenko turns into a no less enthusiastic pro-Russian politician, come a change of mood in the world. It’s almost like an old joke from the Stalin era: “Did you waver with regard to the Party’s general line? I wavered with the general line.”
