The caucus of Republican State legislators met on January 20, Temporary President of the State Senate William H. Robertson presided. Present were all Republican legislators except State Senator Louis S. Goebel[1] (6th D.) and Assemblyman James W. Wadsworth. They re-nominated the incumbent U.S. Senator Conkling unanimously.
Democratic caucus
The caucus of the Democratic State legislators met also on January 20. State Senator Thomas C. E. Ecclesine (8th D.) offered to adopt a prostest against the senatorial election proceedings, claiming that the senatorial and assembly districts were incorrectly apportioned and thus the State Legislature did not represent the wish of the people of the State. The protest was substituted by a resolution to appoint a committee which would elaborate an address on the apportionment at a later date. Ecclesine then marched out, and the remaining legislators nominated Lieutenant Governor William Dorsheimer for the U.S. Senate.

Note: The votes were cast on January 21, but both Houses met in a joint session on January 22 to compare nominations, and declare the result.
Aftermath
Conkling 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.
^State Senator Goebel refused to caucus with any of the parties, but voted for Conkling at the election.
^DeWitt Clinton West (1824-1880), of Lowville, assemblyman 1853
