They’re usually renters but some are champagne socialists. Liberal and especially Nationals voters are more likely to know Indigenous people because they’re more present in the regions, and per capita the regions are way more Indigenous than major cities (many Indigenous also vote for the Coalition too, many also voted No to the Voice, even though many traditionally supported Labor). Labor voters would be more likely to know more people from multicultural communities but not by a huge margin as Liberal voters also live in the cities. The Liberals have a big base in specific multicultural communities too, especially East/South Asian and European voters.
If you read the Greens’ policies, even ignoring the very obvious differences in social policies, they support higher taxes, higher welfare payments, higher public spending and lower defence spending which are all very against economically conservative, pro-business, pro-economy policies. They may not be protectionist lefties like the old Labor Party was back in the day but they still are very economically leftist. Their foreign policy is also quite left-wing, leaning more towards communist powers and dictatorships like China rather than the West.
I describe the Greens and Liberals as holding Eastern and Western foreign policies respectively. Eastern foreign policy generally leans towards China, Iran, Russia, Venezuela, etc while a Western foreign policy supports NATO countries plus their allies like Australia, India, Japan, etc. Those who support Eastern foreign policy generally support Palestine and Russia, while a Western foreign policy would support Ukraine and be either neutral on the Gaza issue but support Israel’s existence, or they would support Israel. However, it’s really more nuanced than that in the West, as the Western left usually doesn’t support Russia, while many ultraconservatives such as many MAGA Republicans and Groypers are supportive of Israel are also supportive of Russia. In South Africa, the ANC holds a clearly Eastern foreign policy: they recognise Venezuela’s government, have little relations with Taiwan, support close ties with China and Russia (albeit whilst still maintaining longstanding Western ties), dodge questions on Ukraine (basically aiming for neutrality) and don’t sanction Belarus or Russia, recognise both states but support Palestine and regularly criticise Israel, etc, whereas the DA holds a clearly Western foreign policy: they support keeping Western ties, don’t agree that South Africa should take Israel to the ICJ for alleged genocide, and perhaps most notably strongly support Ukraine (John Steenhuizen went to Ukraine and met Volodymyr Zelenskyy, the DA-controlled Western Cape was the only province to pass a resolution condemning the war in Ukraine and the DA-controlled Cape Town City Council lit up the Cape Town City Hall in the colours of the Ukrainian flag). The ANC is the governing (albeit internally corrupt) centre-left party and gets its base from poorer Black communities, while the DA is the second-largest party (traditionally the opposition though currently part of an ANC-led minority government) that gets its support from middle-class and upper-class people, usually Asians, Coloureds, Indians and Whites, hence its popularity in Cape Town.
So back to my point about the Greens: they hold economically left-wing views and support Eastern foreign policy. They
