Bob Brown's right (shock, horror): the idea of Peter Garrett running as a Labour candidate, and in a blue-ribbon Labour seat, is pretty weird. The union guys, same article, are probably right, too: there would almost certainly be a backlash from union-inclined voters. Still, I think Labour might slowly realising that the days of being solely built on the unions are gone, and that unless they can draw in voters on policy, they will fade as the unions are, I suspect, fading. All this said, I can't see Garrett running as an ALP candidate, anyway.
