A margin of error of about 1% is a very minor issue in having a democracy. And neither of them had over 50% anyway.

Right now because Americans spend two years every four years fighting an election they are focused on the US (although with some border stuff continuing to persuade Ukrainians that actually Russia are the good guys as they continue to invade that country...) but if you go back a few months there's plenty to underscore the destabilising message that the EU are actually Nazis and if only everybody would put Russia in charge that'd be so much nicer...
