He served in the New York State Assembly from 1784 to 1787 and in the New York State Senate from 1798 to 1808. He was a member of the Council of Appointment in 1799.

Denning was elected as a Democratic-Republican to the 11th United States Congress, beginning on March 4, 1809, but never took his seat, and eventually resigned in 1810.
