In 1987, Bocchini gave up his Assembly seat to challenge Mercer County Executive Bill Mathesius for re-election. Mathesius narrowly defeated Bocchini by 930 votes.[2] Bocchini challenged Mathesius again in 1991.[4] Mathesius announced two weeks later that he would not seek re-election,[5] and the Republican Party nominated Bob Prunetti, a county freeholder from Ewing.[2] Amid a statewide backlash to the policies of the Jim Florio administration, Prunetti defeated Bocchini.
In 2004, Bocchini was appointed Mercer County Prosecutor. He served two five-year terms before informing Governor Chris Christie that he would not accept re-appointment to a third term in office.[1] Before his appointment as prosecutor, Bocchini served as a municipal court judge and municipal prosecutor in East Windsor and Washington Township (today known as Robbinsville).[1]
