With this suppression, if not indeed re-action, of the popular feeling in the North, on the subject of slavery, the two great parties approached the Presidential election of 1848. Each was under peculiar embarrassment in the selection of a candidate, and the presentation of the principles on which support was to be asked. The anomaly presented in the Congressional election of 1846, where an administration conducting a successful war was defeated before the people, promised to be repeated. The Democratic party had precipitated the war, had organized the military force that prosecuted it, had controlled its immense patronage, and had brought it to a victorious conclusion, yet had gained no political strength in the country. The two gallant soldiers who had so largely shared, if indeed they had not absorbed, its glory, were Whigs, and both were in ill-humor with the administration. After the battle of Buena Vista, Taylor's victorious progress had been checked and his army crippled by orders from Washington, which reduced his force, and turned the Regulars over to Scott. Scott ended his brilliant campaign in a flagrant quarrel with the Secretary of War, and was summoned home peremptorily with the prospect of a court-martial. He was ordered to leave General William O. Butler, a Democratic general, in command of the army in the city of Mexico after resistance had ceased. DEMOCRATIC OFFICERS IN MEXICAN WAR. The administration had obviously endeavored from the first to create a Democratic hero out of the war. Authorized to appoint a large number of officers in the increased military force, raised directly by the United States, an unjust discrimination was made in favor of Democrats. Thus William O. Butler, John A. Quitman, and Gideon J. Pillow, prominent Democratic leaders in their respective States, were appointed Major-generals directly from civil life. Joseph Lane, James Shields, Franklin Pierce, George Cadwalader, Caleb Cushing, Enos D. Hopping, and Sterling Price, were selected for the high rank of Brigadier-general. Not one Whig was included, and not one of the Democratic appointees had seen service in the field, or possessed the slightest pretension to military education. Such able graduates of West Point as Henry Clay, jun., and William R. McKee, were compelled to seek service through State appointments in volunteer regiments, while Albert Sidney Johnston, subsequently proved to be one of the ablest commanders ever sent from the Military Academy, could not obtain a commission from the General Government. In the war between Mexico and Texas, by which the latter had secured its independence, Johnston had held high command, and was perhaps the best equipped soldier, both by education and service, to be found in the entire country outside the regular army at the time of the Mexican war. General Taylor urged the President to give Johnston command of one of the ten new regiments. Johnston took
