Baker was elected to the
Tasmanian House of Assembly at the
1928 state election, as one of the
Nationalist candidates in the multi-member seat of
Franklin. He was immediately appointed
attorney-general and education minister in
John McPhee's government. He served until the Nationalist government's defeat at the
1934 election, by which time
Walter Lee had succeeded McPhee as premier. He was viewed as less charismatic than
Australian Labor Party (ALP) premier
Albert Ogilvie, with his colleague
John Ockerby emerging as a more strident critic of Ogilvie in parliament. At the
1937 state election, Baker and the Nationalists received endorsements from Hobart's
Mercury and Launceston's
Examiner, with the latter describing him as "sound, cautious, but presenting a progressive policy". However, Ogilvie and the ALP won a landslide victory. Baker led the Nationalist Party to a further defeat at the
1941 state election. He became the inaugural state parliamentary leader of the
Liberal Party of Australia upon its creation in 1945. Later in the year he announced he would retire from the House of Assembly at
the next state election. He was succeeded as Liberal leader by his deputy
Neil Campbell on 25 February 1946. Baker returned to parliamentary politics in 1948 as an
independent member for
Queenborough in the nonpartisan
Tasmanian Legislative Council. He was elected
President of the Council in 1959, serving until his death in 1968. He was created a
Knight Commander of the Order of St Michael and St George in 1960. ==Personal life==
