The caucus of the Democratic State legislators met also on January 10. State Senator Henry C. Murphy was nominated on the first ballot with 25 votes against 21 for Ex-D.A. of New York A. Oakey Hall. Roscoe Conkling was the choice of both the Assembly and the State Senate, and was declared elected. Notes:
The vote for Ex-Chief Judge Comstock was cast by Henry C. Murphy.
The votes were cast on January 15, but both Houses met in a joint session on January 16 to compare nominations, and declare the result.
Conkling was re-elected in 1873 and 1879, and remained in office until May 17, 1881, when he resigned in protest against the distribution of federal patronage in New York by President James A. Garfield without being consulted. The crisis between the Stalwart and the Half-Breed factions of the Republican party arose when the leader of the New Yorker Half-Breeds William H. Robertson was appointed Collector of the Port of New York, a position Conkling wanted to give to one of his Stalwart friends.
