PRESIDENTIAL ELECTION OF 1864.

The Republican National Convention met at Baltimore, June 7th, 1864, and renominated President Lincoln unanimously, save the vote of Missouri, which was cast for Gen. Grant. Hannibal Hamlin, the old Vice-President, was not renominated, because of a desire to give part of the ticket to the Union men of the South, who pressed Senator Andrew Johnson of Tennessee. “Parson” Brownlow made a strong appeal in his behalf, and by his eloquence captured a majority of the Convention.

The Democratic National Convention met at Chicago, August 29th, 1864, and nominated General George B. McClellan, of New Jersey, for President, and George H. Pendleton, of Ohio, for Vice-President. General McClellan was made available for the Democratic nomination through certain political letters which he had written on points of difference between himself and the Lincoln administration. Two of these letters are sufficient to show his own and the views of the party which nominated him, in the canvass which followed:

Gen. McClellan’s Letters.

On Political Administration, July 7, 1862.

Headquarters Army of the Potomac,

Camp near Harrison’s Landing, Va., July 7, 1862.

Mr. President:—You have been fully informed that the rebel army is in the front, with the purpose of overwhelming us by attacking our positions or reducing us by blocking our river communications. I cannot but regard our condition as critical, and I earnestly desire, in view of possible contingencies, to lay before your excellency, for your private consideration, my general views concerning the existing state of the rebellion, although they do not strictly relate to the situation of this army, or strictly come within the scope of my official duties. These views amount to convictions, and are deeply impressed upon my mind and heart. Our cause must never be abandoned; it is the cause of free institutions and self-government. The Constitution and the Union must be preserved, whatever may be the cost in time, treasure, and blood. If secession is successful, other dissolutions are clearly to be seen in the future. Let neither military disaster, political faction, nor foreign war shake your settled purpose to enforce the equal operation of the laws of the United States upon the people of every State.

The time has come when the government must determine upon a civil and military policy, covering the whole ground of our national trouble.

The responsibility of determining, declaring, and supporting such civil and military policy, and of directing the whole course of national affairs in regard to the rebellion, must now be assumed and exercised by you, or our cause will be lost. The Constitution gives you power, even for the present terrible exigency.
