LeanneDawn asks: "Why are all the competent senior people in the ALP pulling the pin?"
Unlike the Liberal Party, the Labor Party is not a sheltered workshop for senior has-beens.
Labor has the mixture right: The vigour and enthusiasm of youth with a light hand on the tiller from seasoned and experienced hands. Rudd's time in the wilderness did him good. He's learned what to do and what not to do.
Tony Abbott is a know-all who can't learn. Like the Pope, Tony thinks he's infallible.
