Perhaps for the same reason why the press focuses on Trudeau and Squinty McProudBoy for Prime Minister despite them not being electable. The Prime Minister position is appointed. It means nothing to us.
I am sure the answer is, despite meaning nothing, because that is what the audience is interested in. People like to hear about famous people. The guy who lives next door that you can actually elect, and who will actually be important in your life, isn't famous enough for us to want to pay attention.
