Now Meghan McCain is going to defend Joe Lieberman! No do not groan, this will be great! You know, at some point, someone will presumably let Meghan McCain in on the Meghan McCain "in-joke." This will be a very sad day. Exhibit A, from beautiful, young Meg's Daily Beast column: "I find it especially ironic that most of those who criticize Senator Lieberman more often than not have never run for elected office. But as the old saying goes, those that can’t do, criticize." This is like... the rhetorical equivalent of an MC Escher drawing done in lipstick.
