The 1884 Democratic National Convention was held July 8–11, 1884 and chose Governor Grover Cleveland of New York their presidential nominee with the former Governor Thomas A. Hendricks of Indiana as the vice presidential nominee.
These Republicans were called mugwumps, and declared that they would vote for the Democratic candidate based on his integrity.
Seven names were placed in nomination: Grover Cleveland, Thomas F. Bayard, Allen G. Thurman, Samuel J. Randall, Joseph E. McDonald, John G. Carlisle, and George Hoadly.
Nonetheless, Hendricks made an impressive showing on the second ballot but it was not enough to prevent the nomination of Cleveland.
Thomas A. Hendricks of Indiana was overwhelmingly nominated as the Democratic vice-presidential candidate after the names of John C. Black, George W. Glick, Joseph E. McDonald, and William Rosecrans were withdrawn from consideration.
