This interesting, lengthy Bloomberg article about the Australian Senate results, in the September 7, features the leader of the Liberal Democratic Party, who was elected to the Australian Senate from New South Wales. It quotes him as saying he realized he might be able to win, after he discovered that his party had the best position on the ballot.
The Liberal Democrat Party could be considered Australia’s Libertarian Party. It is not associated with the Liberal Party, which is one of Australia’s major parties. Australia uses proportional representation combined with ranked-choice voting for its Senate elections. The smaller parties cooperated to have their voters support each other.
