"This seems somewhat hard to reconcile with the Declaration."

Not in the least. The Declaration is founded on the assumption that rights, and therefore justly wielded powers, are from God.

The Declaration's language is that the power of government is derived from the consent of the governed. This seems quite different from what Leo XIII says: "By this election by which the prince is designated, the rights of principality are not conferred, nor is the power committed, but it is determined by whom it is to be carried on". The Declaration would require that the power be thought to come from God through the consent of the governed, would it not?
