Is 'Angus' the Scottish word for invisible?

Oh Angus, oh Angus. Where for art thou Angus?

It seems to me that the next election will be fought over economics and the cost of living. Or perhaps should be fought over. It is the issue that most (adversely) impacts Australians. It is was is animating Australians. It is the Government’s weakest link.

Yet for some reason, the Opposition is barely making a case. And this is where I am confused. Why is the opposition not all over it? Why is the opposition not talking cost of living every day and every day?
