C'mon mate, even David Speers is saying Rudd "narrowly won". That means Abbott had his head handed to him. Why would he agree to the debate before he had a policy? Just left him having to be negative - then he produced that maniacal laugh which will no doubt get a good run in the election campaign too.
Was interesting to see how they both went - Rudd has had the benefit of these things from 07, was Abbott's first one. He (Abbott) far more suited to the off the cuff thant he prepared - as good as he is at the sound bite, he will need more than that before the election imo.
