The Orange revolution will still be seen as a victory in the Ukrainian elections despite the win of Yanukovych. The Orange revolution will still have made an impact in the elections, and when the next one comes up, there will be a influence seen in them that was produced by the Orange revolution.
Ukrainian President Viktor Yanukovych backtracked on a European trade deal two months ago. Since then, protests have grown increasingly violent in Kiev. The Orange Revolution has boiled over into a red scare against Red Square. Yanukovych supports Russia and his mainstream opposition doesn't. A recently introduced bill limiting public protests in Ukraine won't go over well if it is passed. Otherwise, Kiev may become a ghost town due to all of the five-year sentences for protesters. The Orange Revolution started 10 years ago is coming back with a vengeance, and the president needs to be careful lest his nation turn into another Syria or Chechnya.
The increasing openness and close ties with the EU seemed to be on track, even after Yanukovych was elected in 2010. While the country seemed to be faltering along the old lines, things kept heading the Orange way until the country almost signed a record deal with the EU - Putin subsequently made him a deal, leading to huge protests continuing now over Russia's influence.
With the win of Yanukovych in the Ukranian elections, the Orange Revolution can't be considered a full on success. Such a win is a big blow for the so-called revolution in various ways, especially with how important a loss for Yanukovych would have been. The Orange Revolution can't be called a complete failure either, though.
The Orange revolution will not be seen as victorious in the Ukrainian elections despite the win of Yanukovych. The Orange camp failed to unite and made a lot of broken promises. This will ultimately be seen as a failure. They have already made multiple failures in the past and this is just another one under their watch.
