The map you posted was after these two regions declared their independence and didn’t even participate in that election. About as valid as Saddam’s election results.
My first reply:
1) The regions did not declare independence. Self-proclaimed rulers from Moscow did so.
2) Only the grey area represents those places where no election occurred. Thus, even if we assumed that people there would want to be annexed, they could only succeed in that grey area, not half the country, as you would want us to believe.
3) I can prove that polls of the East and South demonstrate only a minority of support for the separatists, thus you are full of it.
