The committee of detail, after a review of all these considerations, presented a scheme that was well adapted to meet the difficulties of the case. They proposed that the same persons who, by the laws of the several States, were admitted to vote for members of the most numerous branch of their own legislatures, should have the right to vote for the representatives in Congress. The adoption of this principle avoided the necessity of disfranchising any portion of the people of a State by a system of qualifications unknown to their laws. As the States were the best judges of the circumstances and temper of their own people, it was certainly best to conciliate them to the support of the new Constitution by this concession. It was possible, indeed, but not very probable, that they might admit foreigners to the right of voting without the previous qualification of citizenship. It was possible, too, that they might establish universal suffrage in its most unrestricted sense. But against all these evils there existed one great security; namely, that the mischiefs of an absolutely free suffrage would be felt most severely by themselves in their domestic concerns; and against the special danger to be apprehended from the indiscriminate admission of foreigners to the right of voting, another feature of the proposed plan gave the national legislature power to withhold from persons of foreign birth the privileges of general citizenship, although a State might confer upon them the power of voting without previous naturalization. This part of the scheme consisted in the transfer of the power of naturalization to the general government; a power that was necessarily made exclusive, by being made a power to establish a _uniform_ rule on the subject.
