Last week Senator Jacqui Lambie rose to her feet in the red chamber and asked her first set of questions without notice. She was as wobbly as the wooden bike she would later be riding around the forecourt of Parliament, laughing just a little too much -- but she wasn't a disgrace, either, and there's no reason she won't get the hang of it. Yet she is rapidly proving to be the most visibly eccentric of the new crossbench senators, as her two PUP companions, Glenn Lazarus and Dio Wang, are relatively straightforward types, the staged victory hug at the carbon tax repeal notwithstanding.
