The election in New York was held January 17, 1899. Democrat Edward Murphy Jr. had been elected to this seat in 1893, and his term would expire on March 3, 1899. At the State election in November 1898, 27 Republicans and 23 Democrats were elected for a two-year term (1899–1900) in the State Senate; and 88 Republicans and 62 Democrats were elected for the session of 1899 to the Assembly. The 122nd New York State Legislature met from January 4 to April 28, 1899, at Albany, New York. The Republican caucus met on January 12. State Senator Hobart Krum presided. They nominated Chauncey M. Depew unanimously. Depew had been Secretary of State of New York from 1864 to 1865, and was the frontrunning candidate to succeed Thomas C. Platt at the U.S. Senate special election in 1881 when he withdrew after the 41st ballot. Parallel to his political career, he moved up the ladder in the Vanderbilt Railroad System, being President of the New York Central and Hudson River Railroad from 1885 to 1898, and holding positions in dozens of other railroad companies. The Democratic caucus met also on January 12. State Senator George W. Plunkitt presided. They re-nominated the incumbent U.S. Senator Edward Murphy Jr. unanimously. Chauncey M. Depew was the choice of both the Assembly and the State Senate, and was declared elected. Note: The votes were cast on January 17, but both Houses met in a joint session on January 18 to compare nominations, and declare the result. == Ohio ==

In mid-August 1898, Alfred W. McCune decided to seek office as a Democrat for the United States Senate. State legislators had already indicated they would not support the incumbent, Frank J. Cannon for reelection. Cannon, a Republican, had voted against the Dingley Act, which would have raised tariffs on sugar and helped the Utah sugar industry. The Dingley bill was strongly supported by the LDS Church hierarchy, who now opposed his reelection. Other factors were his support for Free Silver; rumors about immoral acts he may have committed while living in Washington, D.C.; and that the Utah legislature was controlled by Democrats. The McCunes were close friends with Heber J. Grant, seventh LDS Church president and an ordained LDS apostle. Although the LDS church had (just weeks before) made a decision to stay out of state politics, McCune asked Grant for the church's assistance in winning office. Grant consulted with Joseph F. Smith (Apostle and sixth LDS president) and John Henry Smith (a member of the Quorum of the Twelve Apostles and the First Presidency of the LDS Church), both of whom supported McCune's senatorial bid. But McCune was not alone in seeking the office. Former Representative William H. King was also running (and backed by two Apostles), as was James Moyle (a prominent attorney and founder of the Utah Democratic Party who was backed by state legislators) and George Q. Cannon (an Apostle and member of the First Presidency). At the time, members of the Senate were still elected by their respective state legislatures. The Utah state legislature convened in January 1899. There were 13 Republicans and 50 Democrats in the state legislature. From the beginning, McCune was considered the leading candidate. But the legislature quickly deadlocked over the election. One-hundred and twenty-one ballots were cast, and no winner emerged. McCune was one or two votes shy of winning on several ballots. on February 18, before the 122nd ballot, state representative Albert A. Law (a Republican from Cache County and a Cannon supporter) claimed McCune offered him $1,500 for his vote. McCune strenuously denied the charge, and a seven-member legislative established to investigate the allegation. The committee voted 7-to-2 to absolve McCune of the charge, and this outcome was announced to the legislature on March 6. Balloting resumed, and on March 8, on the 149th ballot, McCune still lacked enough votes to win office (he had only 25 votes). The legislature adjourned without having chosen a senator, and McCune traveled in Europe for several weeks to regain his health (returning in June 1899). Utah's U.S. Senate seat remained vacant until January 1901. == Vermont ==
