First campaign weeks aren't particularly useful in telling us how elections will go. Former Labor leader Mark Latham had a good start in 2004. The Howard government hit the ground running in 2007 before it all fell apart. Former PM Julia Gillard had a strong first week in 2010 and looked set to blitz Opposition Leader Tony Abbott. In which case, Prime Minister Kevin Rudd, who has had a reasonable first week, might want to be careful: it could be all downhill from this weekend.
