Judging by headlines alone, I’d agree about your assessment of bias.
“World-renowned businessman Donald Trump runs for president” would be biased in favour of Trump (so, Right-biased).
Bias isn’t inherently a bad thing if it’s telling the truth. Yeah, there’s propaganda, but an astute reader can figure it out. Or if you don’t want to read media with a certain bias, then you can skip those publications.
Bias also includes what stories to publish. Right-leaning (and beyond) media probably doesn’t publish a whole lot about the bad things and mistakes Trump did. Yet with completely neutral-sounding headlines, they could still be a biased publication based on the things they choose to publish (or not) and highlight (or not).
