The 1978 United States Senate elections were held on November 7, in the middle of Democratic President Jimmy Carter's term. The 33 seats of Class 2 were contested in regular elections. Special elections were also held to fill vacancies. Thirteen seats changed hands between parties, resulting in a net gain of three seats for the Republicans. Democrats nevertheless retained a 58–41 majority.
The following table indicates the party of elected officials in the U.S. state of Maine:
The 1879 New York state election was held on November 4, 1879, to elect the governor, the lieutenant governor, the secretary state, the state comptroller, the attorney general, the state treasurer and the state engineer, as well as all members of the New York State Assembly and the New York State Senate.
The 102nd New York State Legislature, consisting of the New York State Senate and the New York State Assembly, met from January 7 to May 22, 1879, during the third year of Lucius Robinson's governorship, in Albany.
The 1880 Maine gubernatorial election was held on September 13, 1880 for a two-year term that was scheduled to run from January 13, 1881 to January 3, 1883. The contest resulted in the victory of Greenback and Democratic nominee Harris M. Plaisted, who narrowly defeated incumbent Republican Governor Daniel F. Davis, one of the few times Republicans lost control of the governorship between the founding of the party in the 1850s and the Great Depression.
The 1960 Delaware gubernatorial election was held on November 8, 1960.
The November 1878 New Hampshire gubernatorial election was held on November 5, 1878. Republican nominee Nathaniel Head defeated Democratic nominee Frank A. McKean with 50.26% of the vote.
The March 1878 New Hampshire gubernatorial election was held on March 12, 1878. Republican nominee Benjamin F. Prescott defeated Democratic nominee Frank A. McKean with 50.60% of the vote.
The 1858 Delaware gubernatorial election was held on November 2, 1858. Incumbent Know Nothing Governor Peter F. Causey was unable to seek re-election. His 1854 opponent, William Burton, once again ran as the Democratic nominee. James S. Buckmaster, the former State Treasurer, ran as the People's Party candidate. Burton narrowly defeated Buckmaster to win back the governorship for the Democratic Party.
The 1866 Delaware gubernatorial election was held on November 6, 1866. On March 1, 1865, Republican Governor William Cannon died in office, elevating State Senate Speaker Gove Saulsbury, a Democrat, to the governorship. Saulsbury ran for re-election in 1866, the first Governor to do so since Joshua Clayton in 1792. He faced Republican nominee James Riddle, a prominent industrialist. Saulsbury defeated Riddle by a decisive margin, ushering in a large Democratic majority in both houses of the legislature.
The 1870 Delaware gubernatorial election was held on November 8, 1870. Incumbent Democratic Governor Gove Saulsbury was unable to seek re-election. Former State Senator James Ponder ran as the Democratic candidate to succeed Saulsbury and faced Republican nominee Thomas B. Coursey. As Black Delawareans gained the right to vote, Republicans were confident about their chances, and the Democratic Party responded by presenting itself as the "white man's party." Ponder ultimately defeated Coursey by a wide margin, in part because of low Black turnout and a racist backlash against Black suffrage.
The 1874 Delaware gubernatorial election was held on November 3, 1874. Incumbent Democratic Governor James Ponder was unable to seek re-election. Former county judge John P. Cochran ran as the Democratic nominee to succeed Ponder and faced the Republican nominee, Dr. Isaac Jump. Cochran ultimately defeated Jump, but by a significantly reduced margin from 1870.
The 1882 Delaware gubernatorial election was held on November 7, 1882. Incumbent Democratic Governor John W. Hall was unable to seek re-election. Former State Senator Charles C. Stockley ran as the Democratic nominee to succeed Hall and faced Republican nominee Albert Curry. The Republican Party campaigned on organizing a new constitutional convention and launched a vigorous statewide effort. However, Stockley defeated Curry by a decisive margin and a unanimously Democratic state legislature was elected alongside him, securing the Party's dominance in the state for another four years.
The 1916 Delaware gubernatorial election was held on November 7, 1916. Incumbent Republican Governor Charles R. Miller declined to run for re-election. At the time, the Republican Party was in the middle of a schism that had first developed during the 1912 presidential election. However, the schism did not affect the gubernatorial nomination; though there were rumors that the state party convention might seek to nominate Governor Miller for a second term, former State Representative John G. Townsend Jr. was seen as the frontrunner heading into the convention. He received the nomination without much difficulty and the Republican Party solidified around him its gubernatorial nominee. The Democratic Party nominated former Secretary of State James H. Hughes, and both Townsend and Hughes advanced to the general election.
The 1879 Wisconsin gubernatorial election was held on November 4, 1879. Incumbent Republican Governor William E. Smith ran for re-election to a second term. The Democratic convention initially nominated Alexander Mitchell for Governor, but Mitchell declined the nomination; in his place, Milwaukee attorney James Graham Jenkins received the nomination. Smith and Jenkins also faced a Greenback candidate and a nominee from the nascent Prohibition Party in the general election. Jenkins ultimately won re-election in a landslide, winning 53% of the vote Jenkins's 40%. Reuben May, the Greenback nominee, received only 7% of the vote, a significant erosion from the Party's 15% in 1877.
The 1877 Rhode Island gubernatorial election was held on April 4, 1877. Republican nominee Charles C. Van Zandt defeated Democratic nominee Jerothmul B. Barnaby with 50.93% of the vote.
The 1890 Wisconsin gubernatorial election was held on November 4, 1890.
The 1880 Illinois gubernatorial election was held on November 2, 1880.
The 1884 Illinois gubernatorial election was held on November 4, 1884.
The 1878 Nebraska lieutenant gubernatorial election was held on November 5, 1878, and featured Republican nominee Edmund C. Carns defeating Greenback and Democratic nominee Theron M. Blakely as well as the original Democratic nominee F. J. Mead who still received some votes. Originally, the Democratic party had nominated F. J. Mead for lieutenant governor. However, in late October 1878, the state central committees of the Democratic and Greenback parties met in Lincoln, Nebraska, and decided to replace F. J. Mead with Greenback candidate Theron M. Blakely on the ticket for lieutenant governor.
