It must be conceded to be a most important power, and of a fundamental character. In the light of recent history and of the violence, fraud, corruption, and irregularity which have frequently prevailed at such elections, it may easily be conceived that the exertion of the power, if it exists, may be necessary to the stability of our form of government. The greatest difficulty in coming to a just conclusion arises from mistaken notions with regard to the relations which subsist between the State and National Governments. * * * It seems to be often overlooked that a national constitution has been adopted in this country, establishing a real government therein, operating upon persons and territory and things, and which, moreover, is, or should be, as dear to every American citizen as his State government is. Whenever the true conception of the nature of this Government is once conceded, no real difficulty will arise in the just interpretation of its powers; but if we allow ourselves to regard it as a hostile organization, opposed to the proper sovereignty and dignity of the State governments, we shall continue to be vexed with difficulties as to its jurisdiction and authority. No greater jealousy is required to be exercised toward this Government in reference to the preservation of our liberties than is proper to be exercised toward the State governments. Its powers are limited in number and clearly defined, and its action within the scope of those powers is restrained by a sufficiently rigid bill of rights for the protection of its citizens from oppression. The true interests of the people of this country require that both the National and State Governments should be allowed, without jealous interference on either side, to exercise all the powers which respectively belong to them according to a fair and practical construction of the Constitution. State rights and the rights of the United States should be equally respected. Both are essential to the preservation of our liberties and the perpetuity of our institutions. But in endeavoring to vindicate the one we should not allow our zeal to nullify or impair the other. * * *
