According to the Media Research Center, the media is skewing favorable coverage to Harris by a huge amount. This isn't necessarily a new thing. The corporate media sector has always slanted so far to the left that it's fallen over. However, the lengths they're going to do it is pretty incredible:

Not only has Harris received 66% more airtime than former President Donald Trump, but the spin of Harris’s coverage has been more positive (84%) than any other major party nominee, even as Trump’s coverage has been nearly entirely hostile (89% negative). //

As always, our calculation of spin omits so-called “horse race” assessments (see methodology statement below), but a separate count shows those statements have also favored Harris by a whopping margin (94% positive, vs. just 43% positive for Trump). At the same time, the network coverage has virtually eliminated any discussion of the strident left-wing positions Harris took as Senator or during her 2020 presidential campaign. And while Republican Vice Presidential candidate J.D. Vance and his Democratic counterpart, Tim Walz, have received nearly equal amounts of airtime, the networks have celebrated Walz (62% positive press) and punished Vance (92% negative). //

To give you an idea of how in the pocket they are for Harris, the fact that she hasn't even talked to them has only received 57 seconds of air time over the past four weeks.
