We know Julia Gillard is a weirdo (single, childless, empty kitchen – how weird is that?) but she had ’em howling with laughter at the National Press Club last week. She invited the “boys” troika of Abbott, Costello and Howard to try walking “in the high heels of Australian women” just for a day. Would they – as women – have made the same life choices and decisions, she asked. Would they have married, had kids, and still believed they could one day be prime minister?
