There's almost zero political topics where objectivity is possible. That goal itself is usually already ideology (the goal of unbiasedness often stands in opposition of truth).

Look at global warming: Either it is man-made or not, either it is a problem for our future or not. There's no objective middle ground. Sure, one could simply have news that say "there is a drougth in the center of the US, stronger than other droughts in the last 50 years", without any context. But even this is not objective, because omitting the context of global warming already skews the message.

Or let's use a real historical example: The Soviet Union's invasion into Poland in 1939. Without any context, the SU is clearly the agressor. But with the context of Polands invasion into the SU in 1919 things suddenly look different. And with the additional context of Russia annecting polish territory in the 18th century it looks different again and so on and so on. There clearly is no way to communicate this objectively (i.e. in this case, pro-Russia people could ask why I'd stop here and not with some polish-lithuanian action before the 18th century).
