In the inimitable words of Dick Nixon, Alex Pareene at Salon is getting down to the nut-cutting. The latest, MoDo, is #8 in his list of top 30 hacks. George Will (#11) is in the rear view mirror, as is Peggy Noonan (#10).
Unfortunately, the addition of Laura Ingraham (#9) makes me think that the remaining seven might be obvious picks like Rush Limbaugh or Sean Hannity. I think a real “hack” has to have some Villager cred, which Ingraham does not.
