Kevin won't handle defeat well: brother

''And in terms of the Labor party winning, and even winning his seat, is no lay down misere either,'' Greg Rudd told 3AW radio on Thursday.

On the second-last day of the election campaign, the Prime Minister became the subject of pop-psychology – first from his own brother on radio and, later, at his own hand.

Asked how his brother would handle losing, Greg Rudd said: ''Right from a very early age, Kevin doesn't [sic] handle defeat or rejection well. And that's only because – I wouldn't say that a weakness or anything wrong – it's just that he's filled with so much self belief that what he's doing is right.

''So he won't handle it well and he'll find it difficult to understand why – cause the election won't just be small loss, I think it'll be a larger than small loss – and in his own head I think he'll find it difficult to understand why that's occurred.

''So Kev will have a bit of a learning experience and a bit of a self-education experience to go through but he is an intelligent guy, at heart he's a nice guy and I think he'll come out of it okay, but it will be tough for him initially, yep.''
