I have read(forget where) that Kevin Rudd may want to emulate another Labor PM, Andrew Fisher who had three terms as a PM.
Attached is the terms of that PM.
Obviously Kevin Rudd does not see his circumstances as being different to Fisher's.
I think the fact we need to accept is, while he is in politics he will keep popping up. I think he intends to take his revenge on the plotters of his original dismissal.
