The 1856–57 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 1856 and 1857, and a seat may have been filled months late or remained vacant due to legislative deadlock.https://www.archives.gov/milestone-documents/17th-amendment 17th Amendment to the U.S. Constitution: Direct Election of U.S. Senators (1913) National Archives and Records Administration February 8, 2022 In these elections, terms were up for the senators in Class 1.
The young Republican Party assumed its position as one of the United States's two main political parties. The Whigs and Free Soilers were gone by the time the next Congress began.

New York
United States Senate election in New York, 1857
The New York election was held February 3, 1857, by the New York State Legislature. Whig Hamilton Fish had been elected in 1851 to this seat, and his term would expire on March 3, 1857.
In 1855, the Whig Party and the Anti-Nebraska Party merged in New York to form the Republican Party.
At the State election in November 1855, 16 Republicans, 11 Americans, 4 Democrats and 1 Temperance man were elected for a two-year term (1856–1857) in the State Senate. At the State election in November 1856, 81 Republicans, 31 Democrats and 8 Americans were elected to the Assembly for the session of 1857. The 80th New York State Legislature met from January 6 to April 18, 1857, at Albany, New York.
Preston King was nominated by a caucus of Republican State legislators. King had been a Democratic congressman from 1843 to 1847, a Free Soil congressman from 1849 to 1853, and had joined the Republican Party upon its foundation at the State convention in September 1855. The convention nominated King for Secretary of State, but he was defeated by Joel T. Headley in a four-way race. Secretary of State Joel T. Headley was the candidate of the American Party. State Senator Daniel E. Sickles was the candidate of the Democratic Party.
In the Assembly the vote confirmed the party caucus selections. When State Senator Sickles received votes, the same objection to his eligibility was raised as was in 1833 regarding Nathaniel P. Tallmadge. This time, Speaker DeWitt C. Littlejohn ruled that the objection was "partially tenable and partially not so." However, the Speaker held that any member could vote for anybody, and only if the candidate received sufficient votes to win the election, a decision would be required. Otherwise, like in this case, the eligibility of an also-ran was irrelevant.
In the State Senate, only 24 votes were given. Zenas Clark (Rep.) and John B. Halsted (Rep.) were sick at home. Eaton J. Richardson (Rep.) paired with Sidney Sweet (Am.). Joseph H. Petty (Am.) was absent. William Kelly (Dem.), Mark Spencer (Dem.), and the Democratic candidate Sickles himself, declined to vote.
State Senator Justin A. Smith (Am.) raised the question if the vote for Sickles could be counted. A new State Constitution had been adopted in 1846, which had clarified the question of eligibility of State legislators. Smith quoted from the State Constitution: "No member of the Legislature shall receive any civil appointment within this State, or to the Senate of the United States, from the Governor, the Governor and Senate, or from the Legislature, during the term for which he shall have been elected; and all votes given for any such member, for any such office or appointment, shall be void." Lt. Gov. Henry R. Selden (later a judge of the New York Court of Appeals) decided to count the vote, holding that the United States Constitution described the eligibility for the office and devolved on the State legislatures only the power to prescribe the "times, places and manners of holding the elections for that office", thus not implying a right for the State governments to exclude any person who would be eligible under the U.S. Constitution.Journal of the Senate of the State of New York (80th Session) (pages 171f)
Preston King was the choice of both the Assembly and the Senate, and was declared elected.

1856 United States Senate election in Pennsylvania
The Class 3 election was held on January 14, 1856. William Bigler was elected by the Pennsylvania General Assembly to the United States Senate.U.S. Senate Election - 14 January 1856 http://staffweb.wilkes.edu/harold.cox/sen/PaSen1856.pdf Wilkes University December 22, 2013
The Pennsylvania General Assembly had previously convened on February 13, 1855, for the regularly scheduled Senate election for the term beginning on March 4, 1855. Two ballots were recorded on February 13, followed by three on February 27, 1855. On the fifth and final ballot during this convention, former Senator Simon Cameron had led with 55 votes to future Senator Charles R. Buckalew's 23.
