I guess I always assumed that most economists were political hacks hiding behind academic credentials. I don’t have a problem with academics looking to influence public policy. But it is a fine line between supporting a political candidate and sacrificing professional credibility in service of that end. That’s true whether we are talking about economists going whole hog for Romney and falsely accusing Obama of destroying the economy or whether we are talking about Sean Wilentz embarrassing himself in service of his desire to be the Clintons’ Arthur Schlesinger, Jr.
Of course, one person’s hack is another’s principled academic.
