Politicians are a bunch of wankers. They wouldn't be politicians if they weren't. I don't mean that in a really bad way, I just mean, being a successful politician takes a certain personality type. If you aren't rough as guts, a bit of a prick and full of yourself, you won't survive in Australian politics.
As for compulsory voting, I dig it. You should too.
The ALP (Australian Labor Party) are out "Democrats" (in the US sense; we had a Democrats party here that was something else and basically imploded 5+ years ago anyway). It has its roots in the union movement. The majority of ALP MPs (Members of Parliament, the House of Representatives, often called the Lower House) earned their stripes in the union movement, even now.
ALP support bears some correlation with being "working class" and lower socioeconomic position. Traditional supporters are deeply suspicious of anything that (allegedly) erodes "worker's rights" and of any conservative government.
On the right we have the Coalition, which is two parties: the Australian Liberal Party (don't mistake this with the US meaning of "liberal", they're conservative) and the National Party, which is much like the Liberals but only field candidates in rural seats and have a very rural focus.
Calling this a blue and white collar divide is largely accurate.
The Greens are very much on the left and, like the environmental movements in all developed nations, is largely supported by a young, discontent middle and upper classes. I say this not as a judgement but rather environmentalism is a luxury, meaning you see it in rich not poor countries.
The Greens are basically the "ALP in waiting" and deeply entrenched in university politics (meaning the kind of people who run in or care about student elections).
I think politics among the US electorate is exactly analogous to bikeshed discussions on a mailing list.
In India, its assumed almost sinful to ask for political stance/ "Who are you gonna vote for" in the urban society. (It may be illegal too, not sure)
Granted, I'm not American, but I think I've been here long enough to qualify for all intents and purposes.
You're also correct about generally being able to tell someone's political leaning.
Another thing is that the 2 parties (republican and democrat) are very clearly opposed and distinct. And every republican I know very strongly identifies with being a republican (and my guess is that they vote republican unquestioningly straight across the ballot). Surmise from that what you will.
Voluntary voting in the US has one strange effect: politicians no 1 goal is to get "their" group to vote. Each side has a relatively fixed (and roughly equal) group of voters. Most of them stay home. The side that gets their group voting, even at the expense of a few defections, wins. That creates weird politics.
However, that is not the case everywhere. In lots of places the paradigm is a fixed group (possibly a minority) of voters who shift alliances more easily. A multiparty system encourages this.
I suspect that most defectors are actual abstainers, not defectors.
The recent election was a very close race between the two major parties, and also had one of the highest % of informal votes in recent history, which is some measure of the unhappiness of voters with the choices they were given.
I think everyone should go to Australia at some point, visit the beautiful country. I also think everyone should go to Canada. Amazing places at opposite ends of the world.
So how come nobody has told those internet censor wankers that a joke's a joke, they've had their fun, and now it's time to get back in their box before they feel the back of your hand?
The trouble is, there isn't enough of us who care.
American voting is under-informed and has low turn out, but at least the few percentage of electorate that vote actually care.
Aussies .. I am not sure if they don't care, or if they're just good at hiding their political views. It's far easier to speak to an American and learn about his/her political stances. Aussies are much more opaque, in my experience, and seem to be equally resentful of all politicians.
For all their bureaucracy, Aussies are far more anarchic and egalitarian than any other nation that I am familiar with, except maybe Somalis.
Australians, at least the ones in NSW that I have come to know, consider the government and politicians "a bunch of wankers". They're very pessimistic about the people they elect; which is both nice, and also harmful.
Having said that .. Aussie Aussie Aussie!
[Edit:
People should harden the fuck up and visit Australia; everyone should live there at least once. Just thinking about that place brings a smile to my face. They're a nation of good-natured jokers, thoroughly beautiful I tell ya. But be prepared to be bull-shat left and right; you will have a hard time if you're a self-righteous prick]
