[14] Bishop was defeated by Morris County Freeholder Rodney Frelinghuysen and incumbent Arthur R. Albohn in the 1983 Republican primary for the full term.

[15][16] 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.

[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.

[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.

[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.

Another special convention was then held made up of the Republican County Committee members, in order to fill the vacant Assembly seat.
