Just a short reply; I didn’t use the word ethnicity in my post and that was deliberate. I am not certain that ethnicity is the major fault line in Ukraine - rather a more conscious choice of russiophilia or occidentophilia. Of course history, language, customs etc make up a large part of the reasons behind the choice, but one cannot put equaility between russian speakers and russophiles (eg Julia Tymoshenko).
As to your question, I’m certain that the government supporters are most in favour of quik election. An election would give the new president a democratic mandate, and given that Crimea is “out of bounds” a win for the pro-West candidates is all but assured.
Pro-Russian agitation and estrangement from Kyiv in the east is tied closely with economic hardship and fear about job prospects, according to Rakesh Sharma, director of research at IFES. “The underlying issue is economic in nature because in the east… people were asking why should they be closer to Europe and a lot of their anxiety about association with the European Union came down to a fear that as their local economy is so tied to Russia, they will be the ones to suffer,” he said. “There was definitely an economic rationale being given,” he added.

A majority of those polled in the east said they didn’t feel the Russian language was being discriminated against.
