Most would agree?  Not people who actually listen to NPR.  Its a myth that they skew left.  They actually present news as facts.  

Example: I once heard Scott Simon before the election interviewing people who support both T and C and there was one woman in particular who was a Trump supporter.  Her answers to his questions left her open to be crucified for the fool she was as she obviously knew nothing about the issues and was unable to articulate anything tangible about why she supported Trump.  Any other journalist like Anderson Cooper would have not so coyly made fun of her, or set a trap for her to fall into.  But Scott Simon was a gracious interviewer who actually managed to rehabilitate her with careful questioning so she could at least save face.  I can't think of anyone left or right who would have done what he did.  NPR is as middle of the road as it gets and the reason is, and this is important:

They are not subject to reporting the news in a way that gets the most clicks.
