My take on Bernie is this - he wrote a stupid book about how Dan Rather was satan. He shopped it around to publishers, all of whom recognized it as a poorly written "disgruntled ex-employee" book. The book eventually landed on Rengery's desk, who told Bernie to do a quick rewrite blaming it all on "the liberal media," which for some reason Dan Rather is synonymous with. Bernie complied, though he messed up in a few places - notably when he blamed the "liberal media" for doing things like catering to a wealthy white audience.
Now he's back with another full of shit book, which our full of shit media will promote. Daily Howler takes a look.
