Looking at the popular support behind, the advantage is still with Horace Greeley. President Grant has at his back the diversified army of office-holders, drilled to obey the word of command. The speeches praising him are by office-holders and members of rings. Horace Greeley finds flocking to his cause large numbers of Republicans unwilling to continue the existing misrule, and as allies with them a regenerated party springing forward to unite in this liberal movement. Democrats, in joining Horace Greeley, have changed simply as President Grant changed when he joined the Republicans,--except that he was rewarded at once with high office. The change is open. Adopting the Republican platform, which places the Equal Rights of All under the safeguard of irreversible guaranties, and at the same time accepting the nomination of a life-time Abolitionist, who represents preëminently the sentiment of duty to the colored race, they have set their corporate seal to the sacred covenant. They may continue Democrats in name, but they are in reality Republicans, by the same title that those who sustain Republican principles are Republicans,--or rather they are Democrats, according to the original signification of that word, dedicated to the rights of the people. It is idle to say that Horace Greeley and the Republicans who nominated him are any less Republican because Democrats unite with them in support of cherished principles and the candidate who represents them. Conversions are always welcome, and not less so because the change is in a multitude rather than an individual. A political party cannot, if it would, and should not, if it could, shut the door against converts, whether counted by the score, the hundred, or the thousand; and so we find that the supporters of President Grant announce with partisan triumph the adhesion of a single Democratic politician or a single Democratic newspaper. On equal reason and with higher pride may the supporters of Horace Greeley announce the adhesion of the Democratic party, which, turning from the things that are behind, presses on to those that are before. GREELEY’S ELECTION THE TRIUMPH OF REPUBLICAN PRINCIPLES.
