No, you got that very wrong.
If you really want to ask for values in their ideology, it was the values of fascism (not much in terms of ‘values’ according to today’s understanding)
But it wasn’t the values that brought them votes at all. It was populism and terrorism.
That’s right. The name of the party “national socialists” was chosen carefully.
It seems a contradiction in itself, because nationalists would have meant the far right, and socialists would have meant the far left (and there were actually lots of other parties in between at that time before he took all the power). In truth he wanted to deceive both sides by the name.
