The 1804âÂÂ05 United States Senate elections were held on various dates in various states. As these U.S. Senate elections were prior to the ratification of the Seventeenth Amendment in 1913, senators were chosen by state legislatures. Senators were elected over a wide range of time throughout 1804 and 1805, and a seat may have been filled months late or remained vacant due to legislative deadlock. In these elections, terms were up for the senators in Class 2.
These elections expanded the Democratic-Republican Party's overwhelming control over the Senate. The Federalists went into the elections with such a small share of Senate seats (9 out of 34, or 27%) that even if they had won every election, they would have still remained a minority caucus.

Federalist James A. Bayard was elected November 13, 1804, to finish the term ending the following March.
Federalist James A. Bayard also elected in 1805, to the next term.
In February 1804 two senators were elected to finish vacant terms. The winner of the class 1 seat later resigned, leading to a November special election.
Theodorus Bailey had been elected to the Class 1 seat (term 1803âÂÂ1809) but resigned on January 16, 1804, after his appointment as Postmaster of New York City.
John Armstrong had been re-elected to the class 3 seat to the term that would end March 3, 1807. He resigned February 5, 1802, and DeWitt Clinton was elected February 9, 1802 to finish the term.
Clinton then resigned on November 4, 1803, after his appointment as Mayor of New York City, and Governor George Clinton appointed Armstrong to his old seat to continue the term temporarily until another special election.
Armstrong was then elected to the class 1 seat and so resigned from the class 3 seat.
The first special election was held February 3, 1804, by the New York State Legislature to elect both senators. The class 1 term ended March 3, 1809, and the class 3 term ended March 3, 1813.
