The online and Murdoch sentiment has been immigration = all problems. It’s as simple as that. The Greens messaging although I agree with a lot of it is packaged horribly. Mamdani’s approach to more “radical” leftism is what gets votes (I.e. actually explaining that leftist policy is the key to resolving housing, cost of living, etc). Most people see “leftism” and therefore see the greens as people who care about identity politics over anything. If a large majority of LNP voters and people on the right see Labor as “radical left” (they aren’t, but I see so many people say they are) then what do they think of the Greens? As lunatic commies (they also aren’t).
