Mr Abbot and the ABC?

Those on this forum usually associated with the left say the ABC isn't biased, those from the right say it is. In my view the ABC is definitely biased.

There was a time when the ABC was supported by the National Party. Once upon a time the farmers only contact with the outside world was huddled with his family over the wireless in the evening. Those days are long gone.

So why doesn't Mr Abbott address the problem??
