Apportionment history
When the 40-district legislative map was created in 1973, the 20th was a central Union County-based district including Westfield, Garwood, Cranford, Roselle, Roselle Park, Union Township, and Hillside Township. In the 1981 redistricting, the 20th district received completely new municipalities in eastern Union County including Elizabeth, Linden, Rahway, and Carteret in Middlesex County, New Jersey. Carteret was removed from the district following the 1991 redistricting but Roselle was added from the 21st district.

Changes to the district made as part of the New Jersey Legislative redistricting in 2001, based on the results of the 2000 United States census removed Linden and Rahway (both to the 22nd legislative district) and added Kenilworth and Union Township (both from the 21st district). As part of the 2011 apportionment, Hillside was added from the 29th district, while Kenilworth Borough was shifted to the 21st district.

In the 1973 State Senate race, Alexander J. Menza defeated incumbent Republican Frank X. McDermott, who had served 10 years in office, helping the Democrats gain control of the state legislature for only the third time in the 20th century.

In the 1975 elections, McDermott made a comeback and won a seat in the Assembly. In the 1977 Senate race, Menza chose not to run for re-election (he would run a distant third in the 1978 United States Senate primaries). McDermott ran again for the seat, losing to Democrat Anthony E. Russo.

In redistricting following the 1980 United States census, C. Louis Bassano was shifted to the 21st legislative district, where he ran for (and won) the State Senate seat. Chuck Hardwick was also shifted to the 21st district, where he would win the Assembly seat. With both seats open, Democrats Thomas J. Deverin and Raymond Lesniak, who had both previously served as representatives of the 21st district, won in the Assembly. In the Senate race that year, Anthony E. Russo was also shifted to the 21st district and was replaced by John T. Gregorio, an incumbent Democrat who was shifted from the 21st district.

Gregorio was forced to resign in 1983 after being convicted of conspiracy for concealing his ownership of two go-go bars that were operated by his son. In a June 1983 special election, Lesniak won the seat Gregorio was forced to vacate. In turn, another special election was held in August 1983 to fill Lesniak's vacancy, a race that was won by Thomas W. Long.

After five terms in the 20th district, Thomas J. Deverin was relocated to the 19th legislative district in 1991, with redistricting following the 1990 census tending to favor Republicans. In the 1991 Republican landslide, the 20th bucked the trend, with incumbent George Hudak and Elizabeth Mayor Thomas G. Dunn narrowly holding on to the seats for the Democrats. Hudak and Dunn did not run for re-election in 1993.

In the 1993 election, two former Union County Freeholders, Joseph Suliga and Neil M. Cohen (the latter also served in the Assembly from 1990 to 1992 from the 21st district) were elected. Suliga represented the district in the Assembly until 2002, when he was shifted to the 22nd legislative district as part of the 2001 redistricting, and was elected to the State Senate. Joseph Cryan was elected to the Assembly in 2001, filling Suliga's Assembly seat.

Cohen resigned from the Assembly on July 24, 2008, after images of child pornography were found on his state-issued computer. Democratic committee members from the district selected Annette Quijano to fill Cohen's vacancy.

Joseph Cryan stepped down on January 4, 2015 to become Union County Sheriff. The Union County Democrats selected Roselle Mayor Jamel Holley as his replacement on January 21, 2015.
