NPR is liberal, and I'm deducing that from multiple sources.
I like Breaking Points with Krystal and Sagar - one righty, one lefty, both give their views on a story. Sometimes middle ground is found, always respectful, although Krystal can sometimes be a dink.
I trust Matt Tabbai, Bari Weiss, and Greenwald.
The only biased site I check in with occasionally is the Daily Wire, but I can generally identify the truth parts from the biased.
