It may not even be possible for them to cover politics in a "neutral" way, because anything but the party line on a political issue is heresy to the partisans. If you gave people the hard truths on partisan issues you'd have both sides trying to shut you down because everything you said would be contradicting one side or the other.
Case in point about the difficulty in covering politics in a manner most would consider neutral.
This is the same ABC that reports on the BLM protests in Australia, is happy to parrot the 434 Aboriginals have died in custody since 1991, but fails to include the facts[1]:
58% of deaths were due to natural causes
32% of deaths were due to hanging
5% of deaths were due to drugs/alcohol
4% were due to external trauma
In total, 9 Aboriginals have died in custody from unlawful acts from custodial staff. 10s of thousands of people are violating social distancing orders, because 9 people have been killed unlawfully since 1991. The ABC AREN'T REPORTING THAT. Instead, they have activist after activist deriding the system that is killing black men.
It's all bullshit.
In 2019, the Australian Institute of Criminology did a study on deaths in custody, and its conclusion was:
Indigenous people are now less likely than non-Indigenous people to die in custody, largely due to a decrease in the death rate of Indigenous prisoners from 1999–2000 to 2005–06.[1]
So don't go around telling people the ABC isn't biased.

EDIT: To be clear, this doesn't mean there aren't things we should be doing better, given that Aboriginals make up 28% of the prison population, its just that the current narrative openly being pushed by the ABC and others is pure, unadulterated bullshit.
Or both. Both American parties are full of contradictions.
