In 2010, John F. McKeon, a New Jersey assemblyman, made what he thought was a mild comment on a radio program: Some of the public employees that Gov. Chris Christie was then vilifying had been some of the governor's biggest supporters. He was surprised to receive a handwritten note from Mr. Christie, telling him that he had heard the comments, and that he didn't like them. "I thought it was a joke," Mr. McKeon recalled. "What governor would take the time to write a personal note over a relatively innocuous comment?" But the gesture would come to seem genteel compared with the fate suffered by others in disagreements with Mr. Christie: a former governor who was stripped of police security at public events; a Rutgers professor who lost state financing for cherished programs; a state senator whose candidate for a judgeship suddenly stalled; another senator who was disinvited from an event with the governor in his own district.
In 2011, Mr. Christie held a news conference where he accused State Senator Richard J. Codey of being "combative and difficult" in blocking two nominees. Mr. Codey, a Democrat who had served as governor following the resignation of James E. McGreevey, responded that he had not only signed off on the nominations, but had held a meeting to try to hurry them along. Three days later, Mr. Codey was walking out of an event in Newark when he got a call from the state police superintendent informing him that he would no longer be afforded the trooper who accompanied him to occasional public events -- a courtesy granted all former governors. That same day, his cousin, who had been appointed by Mr. McGreevey to the Port Authority of New York and New Jersey, was fired, as was a close friend and former deputy chief of staff who was then working in the state Office of Consumer Affairs. [...] Later that year, the governor was pressing hard on Alan Rosenthal, the Rutgers political scientist whom Republicans and Democrats had chosen as the tiebreaking member of the commission that was redistricting the state's legislative districts. Mr. Christie wanted Mr. Rosenthal to vote for the map put forward by the Republicans on the commission, but instead he chose the Democrats' plan, saying it offered more stability. Soon after, Mr. Christie used his line-item veto to cut $169,000 for two programs at Mr. Rosenthal's institute at Rutgers.
