In Australia, we have to vote, to avoid a fine. We have the phenomenon of the 'donkey vote', where switched off voters just mark the ballot from the top, 1,2,3 etc. We have preferential voting In Australia, so that if in a particular electorate, one party does not win outright, then the preferences of the least popular party are 'distributed.' If there is still no clear winner, then the new least popular party has its preferences 'distributed', and so on. Candidates have their place on the ballot determined by lot.
If a voter is unimpressed by any party, that voter is free to 'spoil the ballot' by either depositing a blank ballot, or writing some comment on the ballot paper. I did this at our last Federal election, the first time I have ever done it. This is also known as a 'no dams vote', referring to a State plebiscite in Tasmania in the seventies. Voters were given a choice of a lot more dams, or more dams, and many wrote across the ballot paper 'no dams.' The number of spoilt ballots was high enough to make the State government pay attention.
During our last Federal election, last year, the US ambassador to Australia reached the end of his term, and returned to the US. He talked to a journalist at the airport, and said that he was impressed by three things about our electoral process: short election campaigns; compulsory voting, and a Federal commission to determine electoral boundaries, to stop gerrymandering.
We have elections on a Saturday, of course! Why on a weekday?
