Here's a more serious dissection
of the Sean Wilentz piece in Rolling Stone concluding that Bush is the worst president ever.In Wilentz's case, he has all of this data about Bush, but he never sets up what we should expect to find in the data if Bush is indeed the worst president. Thus, the fact that Wilentz has concluded that Bush is the worst really only indicates that Wilentz does not like him. His data is little more than an exhaustive, unconnected laundry list of grievances.
The theme of the piece is that Rolling Stone has brought Wilentz down to its level. That's being charitable to "history will track you down" Sean. Wilentz may be a fine historian when he's writing about the 18th and 19th centuries, but he clearly lacks the ability to detach his political beliefs from his "scholarship" when it come to the modern era.
