Maybe if they don't like the results of the elections, they'll hold new ones until the "good" result comes out (true story, happened in Romania (a EU country) two years ago).
There was proven massive illegal funding of advertising for one candidate and the election result was annulled and rerun under the existing statutes and regulations under Romanian law, ordered by professional judges in a public legal process that was procedurally fair and had appropriate evidentiary requirements.
Stop parroting lines from organisations dedicated to delegitimising liberal democracies.
