Its winners were Democrats John F. H. Claiborne and Samuel J. Gholson. The first session of the 25th Congress was a special session beginning on September 4, 1837, extending to October 16. In November, Mississippi, held the regular election. Seargent Smith Prentiss, a Vicksburg lawyer and Whig, unexpectedly launched a vigorous, partisan campaign. He and fellow Whig Thomas J. Word won in an upset. Claiborne and Gholson then argued that the July result entitled them to serve full terms. With the Whig Party newly organizing, the closely divided House, in which Anti-Masons, Nullifiers, and the Independent tended to align more with Whigs and to oppose Democrats, agreed to hear Prentiss. He spoke for nine hours over three days, packing the gallery, drawing Senators, and earning a national reputation for oratory and public admiration from leading Whigs including Senators Clay and Webster. The Elections Committee then required a third election. Scheduled for April 1838, it confirmed the November result. Both Whigs were seated in May late in the second session, also serving for the third session. |- ! rowspan=2 | (2 seats) |
