His brother, Peter Angelo Cavicchia (1879-1967), served in the U.S. House of Representatives from 1931 to 1937 and was the first Italian American to represent New Jersey in Congress. During Peter Cavicchia's six years as a Congressman, Dominic Cavicchia took over his job as Essex County Supervisor of Transfer Inheritance Tax. Peter Cavicchia resumed his old job after his defeat in the 1936 election.^[1]

In 1938, Cavicchia was elected to the New Jersey State Assembly, representing Essex County. He was re-elected in 1939, 1940, 1941, 1942, and 1943.

He was a member of the Joint Legislative Committee to Study New Jersey's Potable Water Problem in 1940, and in 1941 and 1942, he was a member of the Joint Legislative Committee on Railroad Taxation. He served on the Joint Legislative Committee to hold public hearings on the revision of the New Jersey Constitution. He was not a candidate for re-election in 1945.^[2] Among the Democrats Cavicchia defeated in the 1940 Assembly race was Peter W. Rodino, who would later serve 40 years in Congress.^[3]

In 1952, Governor Alfred Driscoll appointed Cavicchia to serve as Director of the New Jersey Division of Alcoholic Beverages. He held that post until 1954 when the newly elected Democratic Governor, Robert B. Meyner, replaced him with William Howe Davis.^[4]
