You're on a role today. That quote is from the statement for the plaintiff and not from the majority decision written by Chief Justice Taney.
No one, we believe, has ever doubted the proposition, that, according to the institutions of this country, the sovereignty in every State resides in the people of the State, and that they may alter and change their form of government at their own pleasure.As was this:
[48 US 1, 41]
'Undoubtedly the courts of the United States have certain powers under the Constitution and laws of the United States which do not belong to the State courts. But the power of determining that a State government has been lawfully established, which the courts of the State disown and repudiate, is not one of them. Upon such a question the courts of the United States are bound to follow the decisions of the State tribunals.'
[48 US 1, 41]
He also states that the President,
'is to act upon the application of the legislature or of the executive' of the state.
[48 US 1, 43]
"In the course of his reply, Senator Douglas remarked, in substance, that he had always considered this government was made for the white people and not for the Negroes. Why, in point of mere fact, I think so, too."

Basler, ed.), Vol. II, p. 281."Now I protest against that counterfeit logic which concludes that, because I do not want a black woman for a slave I must necessarily want her for a wife. I need not have her for either, I can just leave her alone. In some respects she certainly is not my equal; but in her natural right to eat the bread she earns with her own hands without asking leave of any one else, she is my equal, and the equal of all others."
