I happened to see a few glimpses of the leadership debate between Prime Minister Julia Gillard and contender Tony Abbott.
I didn't hear what they said, which was a boon on two counts: first, I already knew their message in general terms, and the repetition can be wearying. Second, it gave me an opportunity to look at their visual presentation.
They both waggled their heads.
Yet Gillard did it in a reassuring way, while Abbott's head waggling seemed rather agitated. I would expect this debate would only influence those who had not made up their minds. I'm further guessing that those people might not make a lot of sense of the difference between their policies on the basis of what they said. And on what I saw, those swinging voters would have responded better to Gillard.
Later this evening, I heard a few snippets from the debate on the radio. Again, going by just the tone of voice, Gillard sounded more measured, while Abbott was more strident - not in a positive way.
I'm not convinced the debate will have a great influence on the outcome of the election. But if it did - at the margins - it wouldn't bode well for Abbott.
(However, with any luck, the margins are affected by more weighty aspect of the choice between the two parties. That's a hard one, though.)
