Teacher: Now, understand the problem? Solve this instance: Question: How many members did the United Australia Party have when MacDonald was elected to the Senate to represent them? Passage:MacDonald was involved in raising funds for the Nationalist Party from 1925 and by 1930 was its general secretary in Western Australia. He was elected to the Senate at the 1934 election, representing the United Australia Party, although he took his seat early in March 1935, filling a casual vacancy. He was minister without portfolio assisting the Minister for Commerce from November 1937 to November 1938 and then assisting the Treasurer until April 1939. Due to his support for Billy Hughes for the leadership after the death of Joseph Lyons, MacDonald was left out of Robert Menzies' ministries. He lost his seat at the September 1946 election, with his term finishing in June 1947. He failed to get Liberal Party endorsement for the December 1949 election.
