The freshly ousted governor of Illinois exploited its top job, squandered its treasure, hamstrung its legislature, and tarnished its reputation. Rod Blagojevich is a big fish in a shallow barrel, but that doesn't mean we shouldn't fire away. If laughter is the best medicine, Second City's cathartic swipe at America's easiest target should help Illinois recover from a chronic hemorrhage of statesmanship, and since we can't get back those millions Blago illegally spent on FDA-rejected foreign vaccines, satire may be our only cure. This show, now running for a limited time at Chicago Shakespeare Theater, is billed as a takeoff of '70s rock musicals like Jesus Christ Superstar; in that spirit, it amounts to a public crucifixion.
