It's probably important to remember that Russian Officials also celebrated the victory of Barack Obama in 2008. On November 9, 2008, John Hindraker reported in Powerline Blog 
 "Pravda records the enthusiastic reaction of Russian politicians toward the election of Barack Obama. Most perceptive, I think, is the head of Russia’s Communist Party, Gennady Zyuganov:

"All Republican presidents have always defended national interests, ignoring the interests of other countries of the world. The new US president cannot but understand that it is impossible to seek and find answers to many global issues without the participation of such a great country as Russia."

Apparently it's fine for Democrats to achieve approval by the Russians, but Republicans - not so much.
