In 1934, Lennon entered politics and ran for the office of judge of the New Hanover County Recorder’s Court. He was victorious in the election and was reelected for another term in 1938. He served as judge from 1934 to 1942 and later from 1947 t0 1951, in the North Carolina Senate. On July 10, 1953, Lennon was appointed by N.C. Governor William B.
