A special election was held in Delaware's at-large congressional district on October 6, 1807, to fill a vacancy left by the resignation of James M. Broom (Federalist).
In 1806, James M. Broom was re-elected to a second term in Delaware's at-large district.
He'd won his first term in a special election caused by James A. Bayard's election to the Senate.
However, Broom did not serve this second term, instead resigning as well, before the start of the Tenth Congress.
A special election was held for his replacement.
