Plenty of their spokespeople are capable to being careful with their words, and they have lots of experience with woof-whistling. So it might not be nazi in name, just platforming the same policies. But, on the other hand, we have had Nazi electoral parties before: en.wikipedia.org/…/National_Socialist_Party_of_Au… , and we have white nationalist parties still existing: en.wikipedia.org/wiki/Australia_First_Party
