Yes, I know about the Rauschning quote, but I consider its provenance to be dubious enough that I didn't pull it out to bludgeon spacecowboy with and get into a "Hitler agreed with your side!" "No, HItler agreed with your side!" argument. Spacecowboy's claim though, was that Hitler had praised Lincoln in Mein Kampf and approved of his actions in consolidating the federal government, when the passage makes clear he didn't even mention Lincoln.
Hitler
“Individual states of the American Union . . . could not have possessed any state sovereignty of their own. For it was not these states that formed the Union, on the contrary it was the Union which formed a great part of such so-called states.
Certainly all the states in the world are moving toward a certain unification in their inner organization. And in this Germany will be no exception. Today it is an absurdity to speak of a ‘state sovereignty’ of individual provinces. In particular we cannot grant to any individual state within the nation and the state representing it state sovereignty and sovereignty in point of political power.
National Socialism as a matter of principle, must lay claim to the right to force its principles on the whole German nation without consideration of previous federated state boundaries.”
