I read a follow up article that said that a survey of the NPR's main news room revealed of the 87 people who answered, 87 self-identified as Democrat/liberal, and ZERO identified as Republican/conservative.
I'd say I'm shocked, but I'd be lying through my teeth.
I used to listen to NPR back in the 1990s. They weren't too terrible back then, but they started tipping HARD to the left around the time that Bush II went into office, and it just continued falling left faster and faster.
I finally quit listening to them around 2003-2004 when they became absolutely sickening at how far to the left they'd done. Stalin would have been a Conservative to them.
