i'm a green voter but i'd vote for assange in the senate - because he at least stands up for what he believes should be said. the other two main parties in oz are competing with each other to attract the swinging 20% that will give them the election. so they do not care about their electoral base (don't forget we have compulsory voting here, and long may it reign - none of that attracting younger voters crap we had to endure in the UK in 2004).
btw, i believe from what i've read that the charges against assange in sweden are trumped up. the US has put pressure on sweden to deliver another 'example' of how powerful they are.
