To take a single step beyond the text would be to take possession of a boundless field of power.
Thomas JeffersonFor the power given to Congress by the Constitution does not extend to the internal regulation of the commerce of a State (that is to say, of the commerce between citizen and citizen,) which remain exclusively with its own legislature; but to its external commerce only, that is to say, its commerce with another State, or with foreign nations, or with the Indian tribes.
Thomas JeffersonThe division into whig and tory is founded in the nature of men; the weakly and nerveless, the rich and the corrupt, seeing more safety and accessibility in a strong executive; the healthy, firm, and virtuous, feeling confidence in their physical and moral resources, and willing to part with only so much power as is necessary for their good government; and, therefore, to retain the rest in the hands of the many, the division will substantially be into Whig and Tory.
