Warren County Clerk Terry Lee’s decision to resign his post at the end of the year could spark an internal fight among Warren County Republicans. Insiders say two people want to succeed Lee, who has served as Clerk since 1978: Deputy Clerk Patricia Kolb and pharmacist Chad Chamberlain, the son of Freeholder Everett Chamberlain. Governor Jon Corzine will appoint a replacement for Lee, with the advice and consent of the State Senate; state law requires Corzine to name a Republican. Kolb, who has told party leaders she intends to run for Clerk in the June GOP primary, will serve as Acting Clerk until Corzine names a replacement — or until January 2008, if the Governor declines to act. (Corzine did not appoint a new Burlington County Surrogate after the death of Elton Conda earlier this year.) Chamberlain, who serves on the Warren County Municipal Utilities Authority, seems to be actively seeking the post. Lee is backing Kolb. There is some speculation that the younger Chamberlain might get the support of Warren GOP Chairman Douglas Steinhardt, whose law firm would like to receive the elder Chamberlain’s support to become the new County Counsel. Steinhardt is a partner at Florio Perrucci Steinhardt & Fader, with former Governor James Florio and former Warren County Democratic Chairman Michael Perrucci. The current County Counsel is Joseph Bell, a former Morris County Clerk who has held the post for many years.
