There was no rigging or any manipulation of votes. Current and previous government officials were caught bragging about their previous corrupt adventures. The government after some initial shock came up with a story about foreign intervention. Slovenian newspapers and journalist activist carried it all the way to Brussels in order bank on negative emotions about Israel and hopped people will think about that. There was no institutional response, because the current government has cleaned institutions of people not loyal to them. It's a rather sad situation. The society is deeply divided. When similar thing happened in Belgium, the corrupt people were immediately punished and nobody cared who exposed them.
