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.

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.

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.
