Last night, former Illinois Gov. Rod Blagojevich returned to his alma mater, Northwestern University, and to a crowd as skeptical as it was curious to hear how he would defend his legacy in a panel discussion dedicated to ethics in politics. The result for both Blagojevich and the audience was more talk, talk, talk. The students, alumni and Evanston residents treated the event as the sideshow his appearances have become. While the professors on stage earnestly grilled the governor for the most part, they were also sarcastic. Laughter abounded, not sincerity. Blagojevich, no saint himself, largely escaped through his cunning wit and the wag of his tongue.
