When Premier Cahill died on 22 October 1959, he was replaced by Askin's friend and parliamentary contemporary, Robert "Bob" Heffron, which tended to calm his aggression and opposition towards the government. At the March 1962 election, Labor had been in power for 21 years and Heffron had since been Premier for 2 and a half years. Heffron was 72 at the time of the election and his age and the longevity of the government were made issues by the Askin's opposition which described it as being composed of "tired old men". The standing of Heffron's government suffered when the electors rejected its proposal to abolish the New South Wales Legislative Council at a referendum in April 1961, being the first time Labor had lost a state electoral poll in 20 years. Askin's successful opposition campaign centred on warning of a Labor-dominated single house subject to "Communist and Trades Hall influence".
