I think Beazley is a smart guy, met him and have family friends who know him and would like it if he were prime minister. However, I realise that he hasn't got the pezzaz to win an election and having failed two times before, he shouldn't've ever taken leadership again. I like both Rudd and Gillard but if they become leader and deputy respectively their faces will be too unfamiliar to the public and they'll have no chance of getting marginal seats.
I find the ALP to be not left wing enough, while the Greens are a little too left wing, even for me, on some issues. I think what's key to note that even though the ALP won't get a bigger primary vote than before but issues such as the environment, industrial relations will get votes to Greens (who are always preferenced with ALP) and the ALP respectively. The Libs have already ruled out another tax cut and with several interest rate rises (which were necessary and didn't have much to do with the government, like most interest rate changes), they won't have much to shout about. Apparently the next election will be on Austrlian Values and 'the muslims' or something, which would be very sad indeed.
Though it saddens me, I think the coalition will remain in power regaurdless of who leads them to the next election. But it'd be better if Beazley kept going because otherwise, even if Rudd does a better job, people will realise the amount of in-fighting that's going on.
