Labor dont seem very good at scare mongering.
Reds under the bed, blowing out defecits, etc.
They need some scare mongering campaigns on key issues, problem is they are so compromised. Particularly issues such as privatisation, private school funding, private health care funding, refugees, off shore processing, penalty rates, labour hire companies etc. that they really have to where to go.
