It seems Joe McGinniss "leaked" his new, as-yet-unpublished Sarah Palin biography to Doonesbury creator Garry Trudeau, who promptly "leaked" it to his Fox News "reporter" Roland Hedley, who is struggling to find something good to say about it using actual excerpts from the book. The Chicago Tribune is unhappy about this and has declined to run it. Fans of Doonesbury and the First Amendment, in turn, are unhappy with the Tribune. Despite all this unhappiness, it's pretty juicy, funny stuff.
"This week's Doonesbury does not meet our standards of fairness. Please enjoy this substitute strip." - note from Tribune.
