Looking for unicorns
Greg Barns raises the prospect that liberal Liberals might cross the floor to block illiberal government legislation in the Senate. This will take one government senator if the rest of the Senate is opposed, or two if the government can line up an additional vote, say from Family First. As Barns observed, this happened a couple of times under Fraser
And during the 1980s, when the Liberal Party was in opposition, it was liberals such as Ian Macphee, Peter Baume and Fred Chaney who curtailed the impact of the Liberal Party’s social conservatives on matters such as immigration and women’s rights.
Of course Macphee lost preselection and Baume and Chaney were marginalised. But, as Dave Ricardo pointed out in recent comments, if you want to look at what’s happened to the 1980s liberal wing of the Liberal party, you need only look at its remaining representative in Parliament – Philip Ruddock.
