The district had high levels of income on average, but the communities of Dover, Mine Hill, Victory Gardens are well below the state average. The district had a high percentage of Hispanic residents, with Dover having some 60% of its residents as being of Hispanic origin.
Although traditionally thought of as a Republican stronghold, the demographics of the district have trended more Democratic in recent years. At the time of the 2011 legislative apportionment, Republicans held a 16,737 vote (12.0%) registration advantage.[6] By 2019, that advantage was down to 7,801 votes (4.9%).[7] The 25th District had 174,014 registered voters as of December 1, 2021, of whom 60,881 (35.0%) were registered as unaffiliated, 57,063 (32.8%) were registered as Republicans, 54,279 (31.2%) were registered as Democrats, and 1,791 (1.0%) were registered to other parties.[8]
The first iteration of District 25 came in 1973 upon the creation of the statewide 40-district legislative map. The 25th at that time traveled from Maplewood along the western border of Essex County to Fairfield Township (also including North Caldwell, Passaic County's Wayne Township, and Lincoln Park and Pequannock Township in Morris County.[10] In the next redistricting in 1981, the district became based through the center of Morris County running from Harding Township through Morristown, Dover, Boonton, and Jefferson Township.[11] The shape of the district remained mostly the same in the 1991 redistricting picking up Mendham Township, Mount Arlington, and Roxbury Township, but losing Madison and Mountain Lakes.[12]
In the 1993 general election, former Assemblymember Gordon MacInnes defeated Republican incumbent John H. Dorsey by nearly 300 votes, making him the first Democrat in 18 years to win a legislative seat in Morris County.[17]
After Frelinghuysen took office in the United States House of Representatives in January 1995, Anthony R. Bucco was chosen by Morris County Republican county committee members to fill Frelinghuysen's vacant seat in the Assembly.[18] Bucco and Michael Patrick Carroll won the six-way June 1995 Republican primary to fill the district's two Assembly ballot spots, which became open when Albohn decided against running for re-election for a ninth term of office.[19] In this primary, the two winners defeated then Morris County Freeholder Chris Christie and future Assemblyman Rick Merkt.[20] In 1997, Anthony R. Bucco left the Assembly to successfully contest the Democratic-held Senate seat, with Merkt taking the Assembly seat vacated by Bucco.[21]
With Merkt running for the Republican nomination for governor in 2009, the 25th District saw a contested Republican primary with incumbent Michael Patrick Carroll facing Anthony M. Bucco and the younger Bucco's brother-in-law Douglas Cabana, a member of the Morris County Board of Chosen Freeholders. Bucco and Carroll won the two ballot spots and were elected in the general election.[22]
In 2011, Michael Patrick Carroll and Tony Bucco retained their seats in the Assembly, defeating Democratic challengers Gale Heiss-Colucci and George Stafford, while Anthony R. Bucco retained his Senate seat over challenger Rick Thoeni.[23] In 2013, with no Democratic challengers and only token opposition, all three incumbents sailed to victory, earning over 80% of the vote.[24][25]
In 2017, in the closest race since the district was created in 1973, Anthony Bucco narrowly defeated Democratic challenger Lisa Bhimani by just over 2500 votes to retain his Senate seat.[26] In the Assembly race, Carroll and the younger Bucco defeated Democratic challengers Thomas Moran and Richard Corcoran by a similar margin.[27] In 2018, Carroll announced he would not seek re-election in 2019, choosing instead to run for Morris County surrogate.[28] On June 4, 2019, in the first contested Assembly primary in the district since 2009, Tony Bucco and Brian Bergen defeated Aura K. Dunn and John Barbarula to win the Republican nomination for General Assembly.[29]
Senator Anthony R. Bucco died in September 2019. A special convention of the Republican County Committee members from the district met on October 15, 2019, and unanimously selected his son, Assemblyman Anthony M. "Tony" Bucco to fill his father's seat until a 2020 special election. Assemblyman Bucco resigned from the Assembly the day he was sworn into the Senate. Another special convention was then held made up of the Republican County Committee members, in order to fill the vacant Assembly seat. At a November 21 convention, Aura K. Dunn was chosen to serve until the end of the current legislative session, January 14, 2020.[30][31][32] Upon the start of the new session, Tony Bucco declined to be seated to the Assembly seat to which he was elected in November 2019 and a third convention was held on February 1, 2020, which unanimously selected Dunn to serve until a special election in November 2020.[33][34]
