By early 1972, Labor had established a clear lead in the polls; indeed, for the first time since 1955 its support was greater than the combined vote for the Coalition and DLP. Unemployment was at a ten-year peak, rising to 2.14 per cent in August (though the unemployment rate was calculated differently compared to the present, and did not include thousands of rural workers on Commonwealth-financed relief work). Inflation was also at its highest rate since the early 1950s. The government recovered slightly in the August Budget session of Parliament, proposing income tax cuts and increased spending. The Labor strategy for the run-up to the election was to sit back and allow the Coalition to make mistakes. Whitlam controversially stated in March "draft-dodging is not a crime" and that he would be open to a revaluation of the Australian dollar. With the Coalition sinking in the polls and his own personal approval ratings down as low as 28 per cent, McMahon waited as long as he could, finally calling an election for the House of Representatives for 2December. Whitlam noted that the polling day was the anniversary of the Battle of Austerlitz at which another "ramshackle, reactionary coalition" had been given a "crushing defeat".
