when one third of the country is under constant bombardment (by both sides) and not allowed to vote, the other third are refugees living in neighbouring countries, what you sadly have is not an election but a farce.
One third of the country? Please get your facts straight. It's not even one third of the Donbass region that's affected by the hostilities, and Donbass is only 2 of the 24 regions ("oblasts") of Ukraine.
