I want to know the answer to the following question:
Which former liberal founded the Australian Democrats in 1977?
All the background I'm provided with is that "On the other hand, the Liberals have done increasingly well in recent years among socially conservative working-class voters.[citation needed]However the Liberal Party's key support base remains the upper-middle classes; 16 of the 20 richest federal electorates are held by the Liberals, most of which are safe seats.". Is that enough to answer the question?
