The Republicans of the United States, assembled by their delegates in national convention, pause on the threshold of their proceedings to honor the memory of their first great leader, the immortal champion of liberty and the rights of the people--Abraham Lincoln; and to cover also with wreaths of imperishable remembrance and gratitude the heroic names of our later leaders, who have more recently been called away from our councils--Grant, Garfield, Arthur, Logan, Conkling. May their memories be faithfully cherished. We also recall, with our greetings and with prayer for his recovery, the name of one of our living heroes, whose memory will be treasured in the history both of Republicans and of the Republic--the name of that noble soldier and favorite child of victory, Phillip H. Sheridan. In the spirit of those great leaders, and of our own devotion to human liberty, and with that hostility to all forms of despotism and oppression which is the fundamental idea of the Republican Party, we send fraternal congratulations to our fellow-Americans of Brazil upon their great act of emancipation, which completed the abolition of slavery throughout the two American continents. We earnestly hope that we may soon congratulate our fellow-citizens of Irish birth upon the peaceful recovery of home rule for Ireland. FREE SUFFRAGE. We reaffirm our unswerving devotion to the national Constitution and to the indissoluble union of the states; to the autonomy reserved to the states under the Constitution; to the personal rights and liberties of citizens in all the states and territories in the Union, and especially to the supreme and sovereign right of every lawful citizen, rich or poor, native or foreign born, white or black, to cast one free ballot in public elections and to have that ballot duly counted. We hold the free and honest popular ballot and the just and equal representation of all the people to be the foundation of our republican government, and demand effective legislation to secure the integrity and purity of elections, which are the foundations of all public authority. We charge that the present administration and Democratic majority in Congress owe their existence to the suppression of the ballot by a criminal nullification of the Constitution and laws of the United States.
