I doubt it. O'Reilly draws a much hgher-IQ audience, as is evidenced by some of the letters he publishes.
His credibility ranks right up there in their league.
O'Reilly never has to retract anything he says. His accuracy and facts are trustworthy.
BTW, I just heard Savage in the car, and he said that Drudge cannot be relied on to tell the truth, as his book (which Neilsen ranks as #10 this year) wasn't on Drudge's list either.
