Australia's election: 5-week sprint for the top job

Australian Prime Minister Scott Morrison, of the conservative Liberal Party, has called a general election for May 18. He'll face off against Bill Shorten of the opposition Labor Party.

Where things stand: Morrison starts a few points back in the polls. His pitch to voters is that Labor would endanger strong economic growth. Whoever wins might not last long. Australia has had a revolving door of prime ministers in recent years — Morrison is the 5th since 2013.
