In 2014 Freedom Party (FPÖ) has gathered 19.7% of total votes. According to latest estimates (2019), it has gathered 17.2%.
For someone totally outside Austrian politics and hearing only about big things like recent scandal involving the Freedom Party the loss of 2.5% seems rather small. As a comparison in Romania, the ruling party (Social Democrats) has lost about 20% between national parliamentary elections and EU parliamentary elections (~45% => ~25%).
Question: Is there an explanation for Austria's Freedom Party virtually retaining its vote share despite recent scandal?
