<human>: The beginning of the end for Hague came in 1943, when former governor Walter Edge was returned to office. Edge's attorney general, Walter Van Riper, initiated several prosecutions of Hague cronies. Hague retaliated by having his handpicked U.S. Attorney for the District of New Jersey bring federal indictments against Van Riper, but Van Riper was acquitted. Edge also initiated reforms in the civil service, freeing it from Hague's control.  Edge's successor, fellow Republican Alfred Driscoll, succeeded in further curbing Hague's power over state government. He led the effort to implement a new constitution, which streamlined state government and made it less vulnerable to control by locally based bosses like Hague. For example, county prosecutors were now directly accountable to the state attorney general. It also set up a new state Supreme Court, which was given supervision over the state's judges. As the first Chief Justice, Driscoll appointed an old Hague foe, Arthur T. Vanderbilt. Driscoll also installed voting machines throughout the state, which made it harder for corrupt politicians to steal elections.  Seeing the writing on the wall, Hague abruptly announced his retirement in 1947. However, he was able to have his nephew, Frank Hague Eggers, chosen as his successor. It was generally understood that Hague still held the real power. This ended in 1949 when John V. Kenny, a former Hague ward leader alienated by the appointment of Eggers, put together his own commission ticket. Due to the presence of a "third ticket," Kenny's ticket was able to oust the Hague/Eggers ticket from power, ending Hague's 32-year rule. Kenny soon set up a machine which proved every bit as corrupt as Hague's, but far less efficient at providing services. CANNOTANSWER
