Journalists dont need to be right-leaning to be good right-wing journalists.
Your statistics are based off their personal voting intentions. The 'problem' would start at the level where people decide to become a journalist. To be a journalist you have to generally be highly curious about the world and the people around you. This is a trait that is less often displayed in the right, especially the conservative right.
Even the Hero of HotCopper, Mr Andrew Bolt, is an old Labor guy. His journey into being a man of the right probably comes more from a money trail he sniffed out, than his actual personal beliefs, although the two are probably intermixed.
