citation; Ukraine; east vs west

This is a pre-post; in advance of a post coming up, about Ukraine and the west vs east split. I wanted to get some citations for it. The citations basically are simply the past election maps. All of them. Votes for all candidates, in all elections. I've selected a few that make good examples and present them below:
