JAMES TARANTO: President Asterisk: Why the Obama IRS scandal may be worse than “a cancer on the presidency.” “No one can deny that Lance Armstrong and Mark McGwire were highly skilled athletes. But their accomplishments are forever tainted by their use of banned performance-enhancing drugs. The use of the Internal Revenue Service’s coercive power to suppress dissent against Obama is the political equivalent of steroids. The history books should record Obama’s re-election with an asterisk to indicate that it was achieved with the help of illicit means. . . . One thing we have learned from the IRS scandal is that sports journalists are morally superior to political journalists. Whereas the former understand that cheating is an assault on the basic integrity of the sport, the latter all too often treat it as if it were just part of the game.”
