Albo has completely misread the room. The referendum was not a issue that alot of the general public cared about that much.
What's more important, putting food on the table and keeping the lights on, or voting yes/no on a subject that doesn't affect the majority of the population.
Economic issues will always be more important than social issues
Personally I think both parties were more than happy to let this stupid proposal suck up most of the political narrative for a term where almost all Australian's quality of life is heading south but nobody seems to be to blame.
