Lehrer’s leftism is simply more nuanced and understated.
Every time she has a conservative on she will second guess them and play devil's advocate and try to get a gotcha moment, but the interviews with democrats or RINO Republicans and she is all chummy and buddy buddy with them.
There was a time she'd have RINO Lindsay Graham on 2-3 times a week and acting like they were old friends. She has on Col. Allen West and is trying to trip him up. Same thing with Scott Walker and Paul Ryan from Wisconsin (her homestate) where'd you'd expect her to be chummy with them, but outside of a reference to the Packers, she would try to undermine them and try to hit them with the liberal media bias that was attacking them in other outlets and it comes across like the typical scumbag tactic of asking someone how many times he beats his wife. Loaded questions like that make me sick and I am sick of Greta Van Sustenance!
