Menzies manipulated the Opposition on issues that bitterly divided it, such as direct aid to the states for private schools, and the proposed base. He called an early election for November 1963, standing in support of those two issues. The Prime Minister performed better than Calwell on television and received an unexpected boost after the assassination of US President John F. Kennedy. As a result, the Coalition easily defeated Labor on a 10-seat swing. Whitlam had hoped Calwell would step down after 1963, but he remained, reasoning that Evatt had been given three opportunities to win, and that he should be allowed a third try. Calwell dismissed proposals that the ALP leader and deputy leader should be entitled to membership of the party's conference (or on its governing 12-person Federal Executive, which had two representatives from each state), and instead ran successfully for one of the conference's Victoria seats. Labor did badly in a 1964 by-election in the Tasmanian electorate of Denison, and lost seats in the 1964 half-Senate election. The party was also defeated in the state elections in the most populous state, New South Wales, surrendering control of the state government for the first time since 1941.
