The 1869 United States Senate election in New York was held on January 19, 1869, by the New York State Legislature. Incumbent Senator Edwin D. Morgan stood for a second term in office, but lost the support of the Republican legislative caucus in favor of Reuben Fenton.
Republican Edwin D. Morgan had been elected in February 1863 to this seat, and his term would expire on March 3, 1869.
At the State election in November 1867, 17 Republicans and 15 Democrats were elected for a two-year term (1868-1869) in the State Senate. At the State election in November 1868, Democrat John T. Hoffman was elected Governor, and 75 Republicans and 53 Democrats were elected for the session of 1869 to the Assembly. The 92nd New York State Legislature met from January 5 to May 11, 1869, at Albany, New York.
The caucus of Republican State legislators met on January 16, Assemblyman John H. Selkreg presided. All 92 legislators were present. They nominated Ex-Governor Reuben E. Fenton for the U.S. Senate. The incumbent U.S. Senator Edwin D. Morgan was very keen on his re-election, but was voted down. Speaker Truman G. Younglove had held back the appointments to the standing Assembly committees until after the caucus, and subsequent election, of a U.S. Senator, and was accused by the Morgan men to have made a bargain to favor the Fenton men with appointments after the election was accomplished. After the caucus, comparing notes, the assemblymen discovered that some of the most important committee chairmanships had been promised to a dozen different members by Speaker Younglove.
Note: On the first ballot, 93 votes were cast, one too many, and it was annulled without announcing the result. The above stated result transpired unofficially. The blank vote caused some debate if the result was really invalidated by it, but it was finally agreed to take a second ballot.
