The question you're asking is actually very complicated. Pretty much every for-profit media company will have a bias to the right since their goal is to profit today and survive to profit tomorrow. Lowering the taxes for the company and for the wealthy who own large portions of the company are obviously something that the company and the people running the company want, and the platform of the right is consistently to lower taxes on businesses and the wealthy.

The wild thing is the way that the right has shifted in the past 30 years or so. Politicians would stir bigoted voters up with dogwhistle rhetoric while maintaining some level of deniability so that non-bigots would also still feel okay voting for them. This all changed with trump. Suddenly, it was possible to say the quiet part out loud and still get elected. Rather than using mild bigotry as a tool to get into office and then make bank off of bribes and carving out loopholes and conduct insider trading, now moron bigots themselves are running and winning, and they don't actually know what to do or how to do it, so they mostly just shitpost and grandstand because they don't actually know shit about governing.

We're now coming to a point where these companies are hopefully starting to realize that the right is so bad at governing and so damaging with their shitposting that they're actually hurting these companies' bottom line. I wouldn't dare call Democrats "the left" because they're factually a center-right party; the Democrats were posturing to be a sane, safe, profitable alternative. Like it or not, Biden steered our economy back in the right direction, and Harris would've continued on that track while also letting these companies continue to amass wealth. Media companies who saw the forecast and reported with some bias towards Democrats are absolutely not left-leaning. A real left-leaning media company would not be structured like a corporation or traded on the stock market. A real left-leaning media company would be advocating to eradicate the systems as they are and remake them with equity in the foundations. We live in a very right-wing America, and any positive reporting of capitalist America, or gentle criticism of small details of the colonial capitalism of America needs to be understood as right bias. Every time somebody puts the stock market or companies or government contracts or "the economy" over feeding the hungry and housing the unhoused and treating the sick, that is right bias. RATM hit on this perfectly in Bulls On Parade:

Weapons not food, not homes, not shoes
Not need, just feed the war cannibal animal
I walk the corner to the rubble that used to be a library
Line up to the mind cemetery now
What we don't know keeps the contracts alive and movin'
They don't gotta burn the books they just remove 'em
While arms warehouses fill as quick as the cells
Rally 'round the family, pockets full of shells

TL;DR: the litmus of whether your news is biased to the left cannot be determined by whether they nudge for the center-right or the far-right candidate.
