This has been true of most American "journalism" for at least a decade now. Activist journalism has become so common that editorialization is just taken as normal - I doubt that the average person even understands the degree to which news is editorialized. It's next to impossible to find an objective mainstream source these days - for both left and right leaning media.

Probably related to the modern polarization of the nation, though which is the chicken and which is the egg is hard to say.
