As a former politician and someone who has spent plenty of time in front of an ABC microphone, it strikes me that the Liberal party and the public broadcaster have more in common than most of their respective supporters would care to admit when it comes to facing the challenge of their future relevance.

It’s a proposition that might horrify many in Liberal ranks and diehard ABC audiences alike. Yet both institutions face the threat of demographic trends.
