Via Pew Research:

. . . Overall, about seven-in-ten (72%) see news organizations in ideological terms. A 46%-plurality says news organizations are best described as liberal, another 26% say they are conservative. Just 19% say news organizations are best described as neither liberal nor conservative.

The balance of opinion on this question has changed little in recent years, with a plurality consistently describing news organizations as liberal, and about a quarter saying they are conservative.

Not surprisingly, there are wide partisan divides in perceptions of news organizations’ ideology. By a 65%-17% margin, more Republicans say news organizations are liberal than conservative. By contrast, Democrats are divided: about as many say the press is liberal (36%) as conservative (37%). By about two-to-one (47%-23%), more independents say news organizations are better described as liberal than conservative.
