Thomas Stockton, the former New Castle County Register in Chancery, ran as the Whig nominee to succeed Cooper. He faced former State Senator William Tharp, the Democratic nominee. Despite the state's strong financial condition, Whigs came close to losing their grip on power; Stockton only defeated Tharp by 45 votes, or 0.37%. However, Stockton died a year into his term, on March 2, 1846, elevating the Speaker of the State Senate, Joseph Maull, to the governorship, and triggering a special election in 1846. Maull, served just two months before he, too died, elevating State House Speaker William Temple to the governorship.
The 1846 Delaware gubernatorial special election was held on November 3, 1846. A year into the term of Whig Governor Thomas Stockton, elected in 1844, he died, elevating State Senate Speaker Joseph Maull to the governorship.

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.

Hall ran as the Democratic nominee to succeed Cochran. The Republican Party, chastened by its long string of defeats, failed to run a statewide candidate. Instead, the Greenback Party stepped in, and Kensey Johns Stewart ran as the Greenback nominee. The absence of the Republican Party on the ballot caused turnout to crash, and Hall defeated Stewart by the largest margin in state history.
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.
