General Grant accepted the plan of Congress in regard to the reconstruction of the Union. There were three opinions that had obtained a lodgment in the public mind. President Johnson and his supporters claimed that the President held the power by virtue of his office to convene the people of the respective States, and that under his direction constitutions might be framed, and that Senators and Representatives might be chosen who would be entitled to seats in Congress, as though they represented States that had not been engaged in secession and war. Others maintained that neither by the ordinances of secession nor by the war had the States of the Confederacy been disturbed in their legal relations to the Union.
It was the theory of the Republican Party in Congress that the eleven States by their own acts had destroyed their legal relations to the Union; that the jurisdiction of the National Government over the territory of the seceding States was full and complete; and that, as a result of the war, the National Government could hold them in a Territorial condition and subject to military rule. Upon this theory the re-appearance of a seceded State as a member of the Union was made to depend upon the assent of Congress, with the approval of the President, or upon an act of Congress by a two-thirds vote over a Presidential veto.
General Grant sustained the policy of Congress during the long and bitter contest with President Johnson, and when he became President he accepted that policy without reserve in the case of the restoration of the States of Virginia, Georgia, Texas, and Mississippi. Upon this statement it appears that General Grant was a Republican, and that he became a Republican by processes that preclude the suggestion that his nomination for the Presidency wrought any change in his position upon questions of principle or policy in the affairs of government. Indeed, his nomination in 1868 was distasteful to him, as he then preferred to remain at the head of the army. It was in the nature of things, however, that he should have wished for re-election. He was re- elected, and at the end of his second term he accepted a return to private life as a relief from the cares and duties of office. The support which he received for the nomination in 1880 was not due to any effort on his part. Not even to his warmest supporters did he express a wish, or dictate or advise an act. His only utterance was a message to four of his friends at the Chicago Convention, that whatever they might do in the premises would be acceptable to him. His political career was marked by the same abstention from personal effort for personal advancement that distinguished him as an officer of the army. But he did not bring into civil affairs the habits of command that were the necessity of military life. Although by virtue of his position he was the recognized head of the Republican Party, he made no effort to control its action. Wherever he placed power, there he reposed trust.
