I reckon that Labor would love the likes of Clive Palmer to have a go at Julia Gillard, the contrast would be awful for the miners. Clive Palmer looks like a mining boss caricature to begin with, how easy would it be to make him look like a brute, a bully, a "pig of a man" to voters in particular to young female voters when dealing with our new female Prime Minister.
Note; "pig of a man" is being used as an popular female expression not a description of Clive Palmer
