I'd like to see one of the parties actually stand for something beyond simple nay-saying whatever the other has done, trying to scoop up disenfranchised votes.
Also, politics in Australia is often dumbed-down, which I believe is a consequence of compulsory voting. A phrase never used in this country is "voter turnout" because EVERYBODY turns out. Or they get fined.
By forcing everyone to vote, you inherently include those too lazy, too disconnected, or just plain too stupid to be involved. Consequently, there is a very large pool of "lowest common denominators" which the politicians attempt to woo.
Thus, the latest effort to combat climate change, a carbon tax, was shouted down by politicians touring the country, shouting out, "We don't need a great big new tax! Great big new tax!" It honestly wasn't far removed from Citizen Zog.
"Tax bad. Zog good. Vote Zog."
I've seen quite a bit of British politics, working for the BBC, and I am very interested in the current Tory-Lib Dem coalition. Firstly, it seems to be working, which has me astonished; coalitions tend to be rather shambolic. And secondly, to get the best from a right leaning party while using some very liberal members to keep them in check seems quite a good idea.
Sadly, in Australia, it is much like the US. We have a two-party system, and even the next contender is so far behind, they have about as much chance of making a difference as a civil libertarian would have in convincing the Taliban to grant women equal rights.
