I wonder if there isn’t a larger point to be drawn from this.  According to Slate, NRO’s readers are 90 percent conservative, and most of the big name conservative sites hit the 90s.  But an obviously left-leaning site like HuffPo attracts 70 percent liberal and 30 percent conservative.  Doesn’t that suggest that conservatives are far more actively seeking opposition points of view?  I know that’s what I do — I read the NYT and HuffPo to check what the other side is screaming– er, saying.  But does the left do that?  Well, they don’t do it at Drudge, NRO, or RCP — or at least not nearly in the same numbers as conservatives do.
